A periscope is mounted through the roof and into a room within a building, such as a house or the like, whereby people in the building can view scenes outside without leaving the building. The periscope extends from a room in the building, such as a living room of a house, upwardly through any overhead ceilings and floors and through the roof. Further, the periscope extends above the topmost roofline for increased distance viewing or viewing over obstacles. Using en eyepiece at the bottom of the periscope, a user can then see outside areas, including distant areas, while remaining in the comfort of his or her house. The building can be any permanent dwelling structure such as a house, cabin, beach house or the like. Also, the periscope is vertically movable to raise the viewing height and rotatably mounted for full circle viewing.
