St. Patrick's Cathedral stands in the town centre. Built between 1835 and 1847, it is modelled on the 15th century King's College Chapel in Cambridge. It has wonderful examples of work in granite. The monument opposite the cathedral, known as the Kelly Monument, was erected in memory of a local sailor who drowned at sea in 1858.
Also worth seeing is the Courthouse on the corner of Crowe and Clanbrassil Street. It is a fine building of Neo-Gothic design with large pillars on the outside. Also in the square is the stone Maid of Eireann, commemorating the Fenian Rising of 1798.
