The city was founded in the 12th century (the first known written record dates from 1115). The Church of St Peter stands on the site of the original fort. The original name was Luna, which is retained in the name of a local park, Pramen Luna, and accounts for the Moon as part of the town's emblem. The town developed and expanded during the reign of Ottokar I of Bohemia, although the Thirty Years' War depopulated the city. The second half of the 19th century witnessed the economic growth of the area.
The town lies on a railway junction and a factory for overhauling railway engines and rolling stock was established in 1873 which became a major employer and contributed to the town's expansion during the early 20th century. The former state company has now been privatized, but remains the town's largest employer with a workforce of 750.
Other industries include a brewery (from the hops which are grown in the region) and a factory making porcelain electrical insulators for power cables, etc.
The town's architecture was formed mainly in the 19th and 20th centuries when many old buildings were torn down. Nevertheless, the most important architectural feature is Roman Catholic St. Nicholas Church, erected between 1517 and 1537 in the late Gothic style. One of the architects was Benedikt Rejt. It incorporates a tower from an earlier church which was otherwise destroyed along with most of the town by a major fire in 1517.
Parts of the city ramparts remain, as does the Žatec gate which dates from 1500 but was reconstructed in 1872.
An Open-Air Museum of Archeology is located in nearby Březno.
