Amongst the notable buildings in the city's main street, Union Street, are the Town and County Bank, the Music Hall, the Trinity Hall of the incorporated trades (originating between 1398 and 1527, although completely rebuilt in the 1860s), now a shopping mall; the former office of the Northern Assurance Company, and the National Bank of Scotland. In Castle Street, a continuation eastwards of Union Street, is the new Aberdeen Town House, a very prominent landmark in Aberdeen, built between 1868 and 1873 to a design by Peddie and Kinnear.
