Scarlet Devil Mansion

The Scarlet Devil Mansion (紅魔館 Koumakan), also referred to as the Scarlet Manor or Scarlet Mansion, is a European-style mansion owned by Remilia Scarlet. It is located on a ridge on the edge of Misty Lake. From the outside, there are scarlet-colored windows, but there aren't many windows because of the nature of its vampire residents. There are plenty of rooms without windows at all, too. Through the dialogue of Touhou Hisoutensoku and multiple literary works, it can be said that the entrance to the mansion is usually not fully closed. There is a clock tower on the roof, but the bell on it only rings at night. The inside of the mansion is much larger than is apparent from the outside. This is due to Sakuya Izayoi's ability to manipulate time and space.
