general public on 27 September 1953, with construction of Queenstown's first estate, Princess Margaret Estate (named after HM Elizabeth II's younger sister) having already begun last in July last year. By late 1953, a preliminary batch of 3-room flats was ready for occupation. By 1956, work on the Princess Margaret Estate (later shortened to Princess Estate) had more than 1,000 flats comprising one, two and three-room units and 68 terrace houses. A ceremony was held in October that year for Forfar House, a 14-storey block which was a prominent landmark in those days as it was the tallest HDB flat at that point of time. The area continued to develop as a self-contained community. Some of the facilities and amenities developed included the Town Centre and the Swimming and Sports Complex. The former was fully completed in 1969 with three cinemas and a variety of outlets including an emporium, a fresh food market, a maternity and child health centre, a bowling alley and a nightclub cum restaurant. The swimming complex was completed in August 1970. In the 1970s, the success of the new town led to the development of Buona Vista and Holland Village, using the older neighbourhoods of Queenstown as a model. However, by the 1980s, the area had become a mature estate with a higher proportion of senior citizens residing in the area than elsewhere, and a gradual migration of the younger generation into other HDB new towns. Geography Queenstown is bounded by the Ulu Pandan Canal, Ghim Moh Housing Estate and the former Tanglin Camp area to the north, Alexandra Road to the east, Clementi Road to the west and the sea to the south. It covers an area of approximately 2,188 ha. The total population (1990 census) is 126,071 with 31,131 housing units. It consists of 16 subzones, namely Ghim Moh, Holland Drive, Commonwealth, Tanglin Halt, Margaret Drive, Mei Chin, Queensway, Portsdown, Buona Vista, Singapore Polytechnic, Dover, National University, Kent Ridge, Pasir Panjang, Pasir Panjang II, and the Port. Pasir Panjang lies to the south of Queenstown (Pasir Panjang in Malay means "long sandy beach"). The coastline was dotted with Malay villages, the main economic activities being fishing and small-scale agriculture. Only after the war, did the development of the area begin, with bungalows along the coastline being built in the 1950s. Today, Pasir Panjang is a popular recreational area for sea sports and attractions such
