In the years 1637 - 1780, the Jelínek family, whose members worked as excellent carvers and sculptors, went deep into the history of the town. Their works are the culmination of the carving and sculptural art of the 18th century. In 1763, the Italian businessman Josef de Bolzo built one of the first textile manufactories in our country. In 1924, the industrialist Josef Svoboda started the production of popular tractors. Havel. The castle's mirror hall and Loreta's premises have become a popular venue for wedding ceremonies, occasionally concerts and theater events.
