The Cathedral Church of Grammichele was built in 1724. It can be found in the main square atop a flight of steps. The façade is a simple Baroque style - the original upper part having been altered by the architect Carlo Sada. He also added the clock which was at one time set into Town hall building. The interior is large and built on a Latin cross plan with three naves which are divided by five arcades. The dome rises some 39 metres.
