Delft, a town of South Holland, on the Schie, 8 miles N.W. of Rotterdam. It is intersected by canals, and among its notable buildings are the seventeenth-century town-house; a fifteenth-century church, which has monuments to William I. of Orange, who was assassinated at Delft, and to Grotius, and contains the vaults of the royal family; and a church in which Admiral Van Tromp and the naturalist Leeuwenhoek are buried. There are also an arsenal and East Indian College and a Polytechnic. The old manufacture of pottery, for which Delft was famous, has passed away; but there is a manufacture of carpets, casks, and baskets.
