Washington Square, a site listed on the National Register of Historic Places, is located at the intersection of Second Avenue and Union Street in downtown Nashville. Originally consisting of five separate buildings constructed in the 1870s, the property was later renovated into a single structure centered around two atriums. The building underwent further renovations in 2018 and 2022. It offers amenities such as a large conference room and a fitness center, with on-site security and management. Additionally, a 1,500-space parking garage is situated beneath the county courthouse, just one block north.
