The old port of Rorschach, lying at the foot of the Rorschacher Berg in a wide bay, the most southerly in Lake Constance (Obersee), was once an important trading post for the town of St Gallen. Its principal industries are textiles, metalworking and piano manufacture ("Sabel"). The pumping station for the supply of Lake Constance water to St Gallen is here.
The development of Rorschach was closely bound up with economic prosperity of the abbey of St Gallen. As early as AD 947 it was granted the right to hold markets, coin money and levy tolls by the Abbot of St Gallen. The old dock was enlarged in 1484, enabling the town to carry on a considerable trade, particularly in corn. In the 18th C. the linen trade also flourished. In 1803, on the dissolution of the abbey, Rorschach passed to the canton of St Gallen.
At the federal harbor in Rorschach there is a harbor station and the Kornhaus (Granary: built 1746, restored 1956-58), now houses a local museum (closed in winter; well-displayed collection of prehistoric material).

On the hillside above Rorschach is the former monastery of Mariaberg (alt. 440 m/1,444ft), a teachers' training college since 1805, with a beautiful cloister (1519) and a Gothic chapter-house (music room).
To the east of the Rorschach harbor park stretches the beautiful Seepark (fountains) with a lakeside promenade. Not far south of the park and the harbor, the main road runs parallel to the lake with a number of prettily decorated 18th C. houses.
