A stately observatory rises as a rounded stone tower crowned with a ribbed metal dome. Tall arched windows wrap the upper story in a colonnade of pilasters, above a railed balcony gallery and a lower rounded wing.

The classical detailing, weathered blue-grey masonry, and segmented rotating-style dome give it the look of a grand 19th- or early-20th-century astronomical institute. Cornices, moldings, and window recesses are all crisply modeled.

An impressive landmark for a town or campus diorama, a hilltop centerpiece on a model-railroad layout, or an atmospheric scientific building for tabletop settings.
