Gilbert Family Lake House is a summer house owned by the Gilbert Family at Dunham Lake, located some distance away from Mystic Falls. The Gilberts spent many vacations there, and their friends visited and stayed with them occasionally (such as Tyler Lockwood, who knew of the house and was familiar with how to get there).
By chance, Elena and Stefan discovered a secret storage-room, stocked with various weapons intended to be used against vampires. All of it was apparently kept there by Elena's father, Grayson Gilbert. Also hidden there were additional volumes of Johnathan Gilbert's journals. Since Grayson's brother, John Gilbert, had not moved the contents -- especially the journals -- to a more secure location, he may not have even known of the hiding place and that the items were being stored in the vacation home.
Tyler takes Brady to the lake house during the same time and Stefan kills Brady by removing his heart.
Elena and Damon visit the Gilbert Lake House in O Come, All Ye Faithful. After that Jeremy became a hunter, decides to go to the lake house to avoid altercations with Elena and other vampires.
