At its northern end is a landmark statue of Father Mathew. The reason for its curved shape is that it was originally a channel of the River Lee which was built over on arches. The General Post Office, with its limestone façade, is on Oliver Plunkett Street, on the site of the Theatre Royal which was built in 1760 and burned down in 1840. The English circus proprietor Pablo Fanque rebuilt an amphitheatre on the spot in 1850, which was subsequently transformed into a theatre and then into the present General Post Office in 1877. The Grand Parade is a tree-lined avenue, home to offices, shops and financial institutions. The old financial centre is the South Mall, with several banks whose interior derive from the 19th century, such as the Allied Irish Bank's which was once an exchange. Many of the city's buildings are in the Georgian style, although there are a number of examples of modern landmark structures, such as County Hall tower, which was, at one time the tallest building in Ireland until being superseded by another Cork City building: The Elysian. Outside the County Hall is the landmark sculpture of two men, known locally as 'Cha and Miah'. Across the river from County Hall is Ireland's longest building; built in Victorian times, Our Lady's Psychiatric Hospital has now been partially renovated and converted into a residential housing complex called Atkins Hall, after its architect William Atkins. Cork's most famous building is the church tower of Shandon, which dominates the North side of the city. It is widely regarded as the symbol of the city. The North and East sides are faced in red sandstone, and the West and South sides are clad in the predominant stone of the region, white limestone. At the top sits a weather vane in the form of an eleven-foot salmon. Another site in Shandon is Skiddy's Almshouse, which was built in the 18th century to provide a home to the poorest of the city. Cork City Hall, another notable building of limestone, replaced the previous one which was destroyed by the Black and Tans during the War of Independence in an event known as the "Burning of Cork". The cost of this new building was provided by the UK Government in the 1930s as a gesture of reconciliation. Other notable places include Elizabeth Fort, the Cork Opera House, Christ Church on South Main Street (now the Triskel Arts Centre and original site of early Hiberno-Norse church), and St Mary's Dominican Church on Popes Quay.
