The à Âeba (), a river in Middle Pomerania (Poland), originates near the village of Borzestowo west of Kartuzy, passes through à Âebsko Lake and empties into the Baltic Sea. It is 117 km long with a basin area of 1,801 kmò.
The town of LÃÂbork lies on the river à Âeba, while the town of à Âeba on the Baltic coast was originally located west of the present-day mouth of the river.
In the 12th century the lower à Âeba marked the eastern border of the Land of Sà Âupsk-Sà Âawno, ruled by the Pomeranian (Griffin) duke Ratibor I and his descendants, while the territory around the castellany of Biaà Âogarda was a possession of the Pomerelian duke Sobieslaw I of the Samborides dynasty. After Poland regained Pomerelia in 1294, the à Âeba formed the boundary between the Polish part of Pomerania and the Duchy of Pomerania. From 1308, after the Teutonic takeover of Danzig (Gdaà Âsk) and the Treaty of Soldin (Myà Âlibórz), the river formed the western border of the Order's Pomerelian lands with the Duchy of Pomerania until 1466, when Poland regained Pomerelia. From that time the mouth of the à Âeba on the Baltic coast marked the north-easternmost point of the Holy Roman Empire till its dissolution in 1806. The adjacent Pomerelian lands of Lauenburg and Bütow (LÃÂbork i Bytów) became a fief of the Polish Crown with the Second Peace of Thorn (1466).
There is an abundance of architectural and natural attractions near à Âeba, above all the Sà Âowià Âski National Park with its moving sand dunes, about 8 km west of the city. Further objects of interest include:
