Oud Ade
Oud Ade is a village in the Dutch province of South Holland. It is a part of the municipality of Kaag en Braassem, and lies about 7 km east of Leiden.
The village was first mentioned in 1395 or 1396 "Ecclesia de A". The current name means "the old river". Oud Ade developed as a peat excavation settlement, but remained a small linear settlement. It developed into the village in the 1960s by the addition of planned neighbourhoods. The Catholic St Bavo Church was built in 1868.
