St. Gallen was the swiss city chosen to receive the 7th swiss meeting, which took place on May the 4th.
I've been to this city in 2010, also to attend a postcrossing. The card was sent by Grace.
St. Gallen is the capital of the canton of St. Gallen in Switzerland. It evolved from the hermitage of Saint Gall, founded in the 7th century. Today, it is a large urban agglomeration (with around 160,000 inhabitants) and represents the center of eastern Switzerland. The town mainly relies on the service sector for its economic base.
The main tourist attraction is the Abbey of St. Gall, a UNESCO World Heritage Site. Its renowned library contains books which date back to the 9th century. - in: wikipedia
