Looking from an overall perspective, it is readily apparent that the harbor have additional extensions around car park, dock and cafe and shops. The significant alterations we see on the east south side of the harbour.
In 2000, to the south of the harbour where around the water had public beach with a castle. On the other side of the road running by the water stood a lifeboat, while situated in the north east part of the harbour had dock and passenger ferries. The main marina was located in the north west aroubd showers and car park. Opposite to marina had fishing boats where are situated else a car park.
