"Dutch left a lasting impression in the field of architecture. Dutch period buildings still survive in Colombo, Galle and Matara, bearing ample testimony to the fine tastes and aesthetic sense of the Hollander. The place-names of Dutch origin are not many, but are nevertheless significant, and include Hulftsdorp, which is Dutch for 'Hulft's Village', area once served as the headquarters of the Dutch General Gerard Hulft during the siege of Colombo in 1656. Among the other place-names in Colombo, which are of Dutch origin, may be included Bloemendahl (Vale of Flowers) and Wolvendaal (Dale of Wolves). The Beira Lake in Colombo probably takes its name from De Beer who is believed to have been an engineer in charge of the Dutch water defences. In the far north, the Dutch term Delft given to the island of Neduntivu still survives. The Dutch names given to the other islands of Jaffna such as Hoorn, Leiden, Amsterdam, Rotterdam, Middelburg and Enkhuizen have all but disappeared and have been replaced by their local Tamil names."
