According to legend, it is derived from the rain that descended on the region after the blessing of Saint Adalbert in 992 (from the Old Czech pomoknout, i.e. 'to make wet').

The highest point is located in the westernmost part of the municipal territory at 544 m (1,785 ft) above sea level.

The greatest development of the town is connected with the Baroque period, when Nepomuk was an important pilgrimage site.

[3] The I/20 road (part of the European route E49) from Plzeň to České Budějovice passes through the town.

[7] The main landmark of the town centre is the Church of Saint John of Nepomuk.

It was originally an early Baroque church from the mid-17th century, but it was completely rebuilt by Kilian Ignaz Dientzenhofer in 1734–1738.
