The area west of the European Town to the Singapore river between the Fort Canning Hill and the sea was reserved for government use, and the area on the southeast of the river designated the commercial district. Although some European merchants had constructed buildings in the area designated for government and public use before the Jackson Plan was implemented, further such privately owned buildings were not permitted. Nevertheless, the rule was still ignored for a while, for example, the Old Parliament House was originally built as a private home, but was then later acquired by the colonial government. The area now has a high concentration of public and government buildings, including Victoria Theatre and Concert Hall, National Gallery, Asian Civilisations Museum, St Andrew's Cathedral, The Arts House, as well as the Parliament House and the Supreme Court of Singapore.
