The Abattoir, also known as the compound, is a very large house in the French Quarter of New Orleans. It was the primary residence of the Mikaelson family during the 19th century and in the early 20th century. After the Mikaelson siblings, Elijah, Rebekah, and Niklaus were forced to flee from New Orleans after Mikael found them and tried to kill them, Marcel Gerard, who had lived there with the family as Klaus' adopted son, officially took ownership of the home in their absence. Klaus eventually resumed control of the household when he returned to New Orleans nearly a century later in 2011 and regained his rule over the city.
The Vampire Diaries
Marcel took control of the house after the Mikaelsons fled the city in the early 20th century. While he made the house his own, he left Rebekah's room essentially untouched in hopes that she would eventually return home to him.
In The River in Reverse, Klaus decided to move back into the Abattoir after he won control of the city back from Marcel, taking Hayley with him and insisting that she stay at the compound under his protection.
In Reigning Pain in New Orleans, Davina moved in at the behest of Klaus and a reluctant Marcel. Klaus also ended up inviting Elijah and Rebekah to move back in after they make amends regarding a previous quarrel between them. Klaus reminded his siblings that the compound was their family home.
In The Casket Girls, Klaus brought Tim to the compound and used him to lure Davina back to the house after she had run away, following the revelation that Marcel had lied to her about being in danger. Davina, who felt angry and betrayed by Klaus, Elijah and Marcel, confronted them in the courtyard and used her immense strength she had gained from the imcomplete Harvest ritual to punish them for their actions; she forced Klaus to show them all his "real" wolf face before snapping his neck, and forced Elijah to choke on the blood he had fed on earlier. She was in the middle of arguing with Marcel and trying to devise a fitting punishment for him when Rebekah arrived and stabbed Marcel through the chest before Davina could deal with him. Rebekah was later seen carrying an unconscious Davina back to the compound after her friend Tim was killed by Klaus with poison. In a lounge elsewhere in the compound, Elijah went through Davina's sketches and arranged them to reveal she had been sketching evil premonitions she had about Elijah's former lover, Céleste.
In Après Moi, Le Déluge, Davina, who began hemorrhaging magic as the deadline to complete the Harvest ritual came ever closer, was seen vomiting up dirt in her bedroom, and the loss of control of her magical abilities caused New Orleans to experience two strong earthquakes. Elijah brought Sophie to the compound to get information about what was happening to Davina, but Sophie admitted that if the Harvest wasn't completed, Davina's magic would destroy the town. After the Harvest and the Reaping were finally completed and the girls ultimately weren't resurrected as expected, Marcel returned to the courtyard of the Abbatoir and angrily trashed it as a result of how he was overwhelmed by grief from Davina's death.
In Dance Back from the Grave, the compound was shown in flashbacks to 1919, when Elijah and Klaus were brokering deals with the Guerrera family of werewolf mobsters. The compound was also shown to host regular gatherings of witches, vampires, and werewolves in the evening hours. At one such gathering, Marcel confessed to Rebekah that he brought Papa Tunde to New Orleans to run Klaus out of town. Rebekah insisted that the only person Klaus has ever feared was their father, Mikael, so Rebekah suggested that they involve a powerful witch, Genevieve, who was also in attendance, to help them find him and bring him to town to run Klaus out, allowing the two of them to finally be together. In another flashback, a welcome home party was held at the compound for Marcel, who had just arrived home after being deployed overseas as an Army soldier in World War I.
In Moon Over Bourbon Street, Elijah threw a party at the compound in an attempt to bring all five factions of the city (the Originals, the vampires, the werewolves, the witches, and the humans) together so they could ultimately broker a new peace agreement to help heal New Orleans. After Hayley gave an inspiring speech, the factions were finally able to agree on a treaty, and all of the representatives of the various factions (Elijah and Klaus, Diego, Hayley, Genevieve, and Francesca, respectively) eventually signed the agreement in their own blood.
In The Big Uneasy, Elijah revealed his intention to renovate their home, citing the fact that Marcel and his vampire minions had abused their home for the better part of a century as the reason for doing so. Klaus was initially against the idea, but after Elijah argued that he refused to live in squalor, Klaus ended up agreeing with him.
In An Unblinking Death, Klaus is seen searching through his bookshelves in the study of the Abbatoir while he searches for his mother's grimoire, but Elijah eventually revealed that he had hid it from him, as he knew that Klaus had a deal of some kind with the Crescent werewolf clan and didn't want him to be able to continue his plans. However, after the bombings in the Bayou, Elijah ultimately decided that Klaus was right to want to empower the Crescents, including Hayley, with moonlight rings, and gives him the grimoire.
In A Closer Walk With Thee, Genevieve informed Elijah and Klaus that the Other Side was falling apart, and that it's not just their father who is afraid of being sucked into oblivion. Later, after Hayley, who was hexed by Monique, passed out at Father Kieran's funeral, Elijah and Klaus brought her back to the compound. Genevieve performed a spell to figure out what had been done to Hayley, and once she had, she sent Klaus and Elijah to get her gris-gris pouch. In the meantime, Hayley was seen in the compound while she was on the Other Side, where she was attacked by an angry Mikael, who sought to kill Hayley and Klaus' then-unborn daughter. After Hayley was brought back by Genevieve, she was seen sitting in her bedroom when Klaus came to talk to her. She informed Klaus she had decided to come back to the compound, and he shows her the nursery he has prepared next to her room, assuring her that he would like her to continue living with them after the baby was born, so they could all live together in their family home. At the end of the episode, Elijah visited Hayley in her room, and confessed that in his more than one thousand years of life, he had never been so afraid as he was when he thought Hayley was dying. He was about to leave, afraid to admit his feelings, but Hayley stoped him and kissed him passionately.
In The Battle of New Orleans, Marcel tried to reclaim control of the French Quarter from Klaus and Elijah after learning about their plans for the moonlight rings, which would result in the extinction of vampires. He and his army enter the Abattoir to stop Genevieve from doing the spell, and Marcel led Klaus away to battle him one-on-one while the rest of the vampires fought Elijah to kill Genevieve and destroy the grimoire. However, they underestimated both Elijah and Klaus' fighting prowess, and Elijah easily bests all of the vampires. It was then that Francesca and her brothers revealed that they weren't humans, but actually Guerrera werewolves who had made a secret deal with Genevieve to take the moonlight stones for themselves in exchange for giving Hayley to the witches. Francesca and her brothers took possession of the stones and triggered their werewolf curses before using their new abilities to bite and attack Elijah and the wounded vampires. Marcel, having also been bitten during his fight with Klaus, returned to the compound to find all of his vampires dead or dying from werewolf bites. Cami tended to Marcel's wounds until Elijah, who had just woken up, realized that Hayley was gone and confronted Marcel about it. He was sure Marcel had taken her, but Cami defended him as they explained what had really happened.
In From a Cradle to a Grave, a flashback showed Hayley and Klaus in their baby's nursery, where Hayley wrote her soon-to-be-born daughter a letter. In the present time, all of Marcel's vampires were dying from their werewolf bites. Davina arrived to save Josh from his werewolf bite with a cup of Klaus' blood she managed to salvage from the street with a spell. Once Hope had been saved by Marcel, he returned to the compound in hopes that he could leverage her for Klaus' blood to heal his vampires, only to learn that they had all been brutally murdered; they assumed it had been the werewolves, finishing off what they had started the previous night, but in reality they had been killed by Mikael. Once the fight was over, Klaus and Elijah were seen discussing the plan for the baby in Hayley's bedroom, while Hayley rocked Hope in a rocking chair in the nursery.
In Rebirth, it was revealed that the Mikaelson compound had closed their doors to the public following the fight in the courtyard and the (faked) "death" of their daughter, who was claimed to have been killed by the Guerreras. During the time following the attack, Klaus, Elijah and Hayley had become recluses in the compound, leaving only for business matters, or, in Hayley's case, to visit the Bayou. Once Francesca learned about the existence of the indestructible White Oak Stake, she ordered an attack on Klaus at the compound during the full moon, knowing that he would be weakened by the use of their moonlight rings, which drew on the strength of his blood. Unbeknownst to the Guerreras, this was all a trap to bring the pack to them so that Elijah, Marcel, and Hayley could take their moonlight rings and return Klaus' strength. The trap was also to finally kill them for their role in Hope being forced to be sent away, and for aiding in Hayley's murder, which led to her transition into a hybrid. In the end, all of the Guerrera werewolves with the moonlight rings were killed except for Oliver. Elijah was also seen trying to pack up the nursery at the compound, though Hayley became angry and ordered him to stop. After the battle against the Guerreras, Hayley angrily started destroying the furniture in the nursery, because she was so overwhelmed with feelings since becoming a hybrid, and was appalled at the fact that she had killed nine of her own people that night.
In Savior, Camille has been staying for weeks so that Klaus can keep an eye on her.
In Alone with Everybody, Kol is seen to have moved in his family home since he came back. He has now his own bedroom.
In The Devil Comes Here and Sighs, it is revealed that the ownership of the Abattoir has been signed over to Freya to fortify the mansion's defenses. This means that Freya and only Freya can invite vampires in.
In The Bloody Crown, Marcel nullified the deed to the Abattoir and foreclosed it, allowing any vampire, including the army of Klaus' former sirelings, to enter without an invitation. The former sirelings later destroy the Abattoir.
In Gather Up the Killers, five years have passed since Klaus' imprisonment and the other members of the Mikaelson family forced to leave New Orleans until a cure for the Upgraded Original Vampire's venom can be found. The Abattoir has since been abandoned and now serves as Klaus' underground prison.
