One building on High Cross has certain significance; the Georgian Assembly Rooms building, now a bakery, was built in 1780 and was the centre of Truro's high society, containing the Old Assembly Halls and also a theater. There are two busts above the first floor windows, one of the actor and theatrical producer David Garrick, and the other of William Shakespeare.
At the edge of the square near Pydar Street, there is an ancient Celtic cross, recently unearthed during a development project in the city. It was then restored and displayed at High Cross, where it previously stood in the city's earlier years.
The cobbles in High Cross were concreted over when Queen Elizabeth II visited the city in the 1970s, and they were restored afterwards.
