About this build

An observatory: a round tower of dark stone with copper bands under a dome of green copper split open by a slit, with a great brass telescope of gold and copper reaching out of it to the sky. A ladder climbs the middle from the library below, with its shelves of books and a desk, to the star room, where a lectern, a map table and a star chart laid on the floor wait under the dome. Lamps light the path and a sundial stands in the grass.
