The name is also similar to that of the French commune Lewarde, located in the Nord Department, an originally Flemish-speaking area annexed to France in the 17th century. Western Flemish was related to Frisian and also to Saxon up to the 11th century. History The oldest remains of houses date back to the 2nd century AD in the Roman era and were discovered during an excavation near the Oldehove. Inhabited continuously since the 10th century, the city's first reference as a population centre is in German sources from 1285, and records exist of city privileges granted in 1435. Situated along the Middelzee, it was an active centre of maritime trade. The waterway silted-up in the 13th century. The Grote of Jacobijnerkerk () is the oldest building in the city. The 15th century was the period of the two opposing Frisian factional parties Vetkopers and Schieringers. The bastions and a moat were built in the period 1481–1494.
