town, Orne département, Basse-Normandie région, northwestern France. Alençon lies at the juncture of the Sarthe and Briante rivers, in the centre of a plain ringed by wooded hills. It is known for its tulle and lace (especially point d'Alençon), introduced from Venice in the mid-17th century. Incorporated in the duchy of Normandy in 911, it was capital of the county and duchy of Alençon and passed to the French crown in 1549. The castle, only parts of which remain, was taken by William of Normandy in 1048; law courts have been built into the castle's living quarters. The town's Church of Notre-Dame dates mostly from the 15th to 17th century. The medieval Maison d'Ozé and the 18th-century town hall survived heavy bombardments in 1944. Recent industrial development includes the manufacture of electrical products and plastics. Alençon is an administrative centre and has a branch of the University of Caen. It is also a small but important tourist centre, lying at the heart of the Normandie-Maine regional park. Pop. (1999) 28,935; (2005 est.) 28,400.
