The municipal territory lies in three geomorphological regions: the southern part lies in the Doupov Mountains, the central part lies in the western tip of the Most Basin, and the northern part lies in the Ore Mountains. The highest point, located on the northern municipal border, is the hill Volyňský vrch at 727 metres (2,385 ft) above sea level.

## History

Between 1150 and 1250, a settlement and a small monastery were established by Benedictines from Postoloprty. It is not known, whether the settlement or the monastery is older. The first written mention of Klášterec is from 1352.
The Hussite Wars did not affect the town too much. In the half of the 15th century, Klášterec was already referred to as a market town. At the beginning of the 16th century, the town wall was completed. During the 16th century, houses were built behind this wall, which created the so-called "lower town".
In 1794, the oldest porcelain factory and the second oldest factory in Bohemia overall was founded. In the years to come the town grew in importance as one of the earliest European regions of porcelain production and became famous for its porcelain. The original owners of the Klášterec nad Ohří porcelain factory, the Princes of Thun und Hohenstein, were in 1945 expelled from Czechoslovakia along with the remaining ethnic German population.
Over the years, a number of settlements were attached to Klášterec nad Ohří, most of them only in the second half of the 20th century, some of then already as extinct villages. Šumná and Útočiště have been administered by Klášterec since its inception, and Lestkov has belonged to Klášterec since the beginning of the 17th century. In 1950, Miřetice was joined, in 1961, Klášterecká Jeseň (including the area of extinct villages of Kunov and Vysoké), Ciboušov, Rašovice and Suchý Důl were joined, and finally in 1988 Hradiště (including the area of extinct villages of Pavlov and Potočná), Vernéřov and Mikulovice were joined.
