An inn called the Aldgate Pump was opened by Richard D. Hawkins, a well-known publican, in 1864. The pump which Hawkins had installed outside the hotel (and which gave the hotel its name) became a popular place to water the
horses and
bullock teams which passed through the area, The Hills Land and Investment Company subdivided land in the Aldgate area and laid out part section 92,
Hundred of Noarlunga for settlement in 1882, naming the town after the hotel.
21st century Aldgate's
drainage system has suffered substantial problems and has been the result of drastic
flooding through the main street. One of the worst cases of this occurred at around 8:00AM on 8 November 2005, which left most of the businesses in the main street flooded with significant damage. A recent ongoing project around Aldgate has been upgrading the drainage system. In 2009 and 2010, the intersection of
Mount Barker Road,
Strathalbyn Road and Kingsland Road in Aldgate was upgraded and streetscape works were carried out throughout the township. To make way for the roadworks, the pump which was the centrepoint of the town was temporarily removed. It was reinstalled in May 2011 by the
Adelaide Hills Council and now sits atop a pedestal on the footpath in the main street. A new
fire station for the
Aldgate Country Fire Service was completed in August 2009. ==Railway==
