Here are shots from inside the Portland Observatory in Portland, Maine; I posted a photo of the tower itself a few days ago. The tower is 86 feet tall, and made of wood.
Originally built in 1807, the most recent restoration was completed in 2000, and the replacement wood can be distinguished by its lighter color.
The tower is not anchored to the ground; instead it's held in place by rock ballast beneath the main level. You can see the rocks through this opening and mirror in the lower level. Believe it or not, this has held the tower secure through numerous hurricanes!
Born in London, I've lived in The Netherlands, New York, and Washington DC. Now I've settled down in Colorado and love taking pictures. Until October 2014 I used a Nikon D40X, but now it's a Nikon D5300. I do almost no photo editing - occasionally I will crop or remove a dust spot, but that's all. What comes out of the camera is what you see here.
