As the city's wealth increased, its centre expanded westwards as the lush Victorian architecture of what is now known as the Merchant City area began to spring up. New public buildings such as the City Chambers on George Square, Trades Hall on Glassford Street, and the Mitchell Library in Charing Cross epitomised the wealth and riches of Glasgow in the late 19th century with their lavishly decorated interiors and intricately carved stonework. As this new development took place, the focus of Glasgow's central area moved away from its medieval origins at High Street, Trongate, Saltmarket and Rottenrow, and these areas fell into partial dereliction, something which is in places still evident to the present day.
