Delfshaven (Dutch pronunciation: [ˌdɛl(ə)fsˈɦaːvə(n)] ⓘ) is a borough of Rotterdam, Netherlands, on the right bank of river Nieuwe Maas.
Delft itself was not located on a major river, so in 1389 a harbour was created about 10 km (6 mi) due south of the city, to be able to receive seafaring vessels and avoid tolls being levied by the neighbouring and competing city of Rotterdam.
Since then, the town's Oude Kerk has also been known as the Pelgrimskerk, or in English, the "Pilgrim Fathers Church".
It features modest local museums, a brewery and various dining and drinking facilities.
Later during the Second World War, the area around the Visserijplein and other parts of the western city of Rotterdam were destroyed by Allied bombing on 31 March 1943.
