Koge is a town in Roskilde County on the east coast of the island of Zealand in east Denmark. Koge is one of the best preserved medieval towns in Denmark. It was founded by royal orders, close to the coast and with a regular street system round a large central market square. The town was granted an municipal charter in 1288 and fortified with ramparts, moats and large town gates. Around year 1400 Koge had become an enterprising commercial centre, and over the following 250 years it developed into one of the leading market towns on Sealand. No other town has got so many well-preserved half-timbered old houses and medieval cellars as Køge, and in Kirkestræde you will find Denmark´s oldest house with a date on it (1527). Today, Koge is once again an active commercial centre and port, with an extraordinarily well-preserved city centre, created by visionary people more than 700 years ago.
