At the middle of quaint St Gallen, an eastern Swiss metropolis that enlarged from the 7th century hermitage lays the Abbey of St Gall, a UNESCO World Heritage Site and expensive remnants of a typical Carolingian monastery. Its library, with illustrative Baroque architecture and Rococo beautification, is summoned one of the richest and most widespread medieval collections in the world, while the Cathedral, apart from its proficient design and imaginary adornment, features one of the three oldest enduring bells in Europe, brought by Gallus himself on his seventh-century pursuit from Ireland.
