And although it would seem that most places in Switzerland are crowded with tourists, there are several cities or towns where foreign visitors do not come too crowds. If you are looking for peace and quiet, be sure to visit Spiez , which is located on Lake Thum. Numerous vineyards, a castle and a historic church create an idyllic setting. It is also worth visiting Sankt Gallen . There is a library in the abbey in which 170,000 documents are kept. Experience a typical Italian Mediterranean atmosphere when visiting Lugano , and one of the largest Swiss castles can be found in Gruyeres .
