The Kattegat (Danish), or Kattegatt (Swedish) is a sea area bounded by Jutland (Denmark and extreme north Germany), and Scania, Halland and Bohuslän (Sweden). The Baltic Sea drains into the Kattegat through the Oresund and the Danish Straits. The Kattegat is a continuation of the Skagerrak and may be seen as either a bay of the Baltic Sea, a bay of the North Sea, or, in traditional Scandinavian usage, none of these.

Geography

According to the definition established in a 1932 convention signed by Denmark, Norway and Sweden (registered in the League of Nations Treaty Series 199 - 1933), the northern boundary between Kattegat and Skagerrak is found at the northernmost point of Skagen on Jutland and the southern boundary towards Oresund is found at the tip of Kullen Peninsula in Scania.

Waterways that drain into the Kattegat are the rivers of Göta älv at Gothenburg, together with the Lagan, Nissan, Ätran and Viskan from the province of Halland on the Swedish side, and the river of Gudenå from Jutland, in Denmark.

The main islands of the Kattegat are Samsø, Læsø and Anholt, where the latter two, due to their dry summer climate, are referred to as the Danish desert belt.

A number of noteworthy coastal areas abut the Kattegat, including the Kullaberg Nature Reserve in Scania, Sweden, which contains a number of rare species and a scenic rocky shore, the town of Mölle, which has a picturesque harbour and views into the Kullaberg, and Skagen at the northern tip of Denmark.

Currently, a proposed bridge from Jutland to Zealand, across the southern part of Kattegat is under political consideration in Denmark.

Etymology

According to Den Store Danske Encyklopædi and Nudansk Ordbog, the name derives from the Dutch words Kat (cat) and Gat (hole). It refers to late medieval navigation jargon, when captains of the Hanseatic trading fleets would compare the Danish Straits to a hole so narrow that even a cat would have difficulty squeezing its way through on account of the many reefs and shallow waters. At one point, the passable waters were a mere 3.84 kilometers (2.38 miles) wide.

An archaic name for both the Skagerrak and Kattegat was the Norwegian Sea or Jutland Sea (Knýtlinga saga mentions the name Jótlandshaf). The name of the Copenhagen street Kattesundet is derived from same root.
