Collinwood Mansion

Garden terrace — Located just outside the terrace. It has a water fountain, small plaza and a gazebo.

Tower room — Structurally, the house was constructed around a large central tower that contained an attic room. In 1796, this room was used temporarily to house Barnabas Collins' coffin. In 1897, Judith Collins Trask housed the crazed Jenny (wife of Quentin) there.

Quentin Collins' study — A large private study used by Quentin in 1897. Judith Collins, Quentin's elder sister, had the entrance sealed up after servant Beth Chavez shot and killed Quentin in the tower room. In 1968, David Collins and Amy Jennings discover a hole in the wall that leads to the room. In there, they find Quentin's skeletal remains. The two children then encounter and become possessed by the spirits of Quentin and Beth Chavez.

Parallel Time room — One of the strangest rooms in the house, this grand bedroom suite was a conduit to an alternate reality. Normally it was one more unused east wing room. However, when viewing it from outside the doorway, characters could see the Collins family members of another world. In that other Collinwood, the room was the private quarters of Angelique, who was the first wife of Quentin (the lord of the manor in this reality) and mother of Daniel (David). The inhabitants of that other reality were unaware that they were being observed (although Angelique and a few other Parallel Time characters saw into the “normal time” counterpart room occasionally). An invisible barrier usually kept the two worlds separate, but Barnabas and Julia were both able to pierce it. When a fire destroyed the Parallel Time Collinwood, the gateway to that other world was (presumably) broken for good. However, in 1840, Daphne Harridge "discovered" it as well, and Lamar Trask pierced the barrier just before dying.
