Castle park in Třeboň, Castle park near Svět pond, Třeboň, Czech Republic

Castle park in Třeboň is a sprawling green space with winding paths surrounding the castle and connecting different sections planted with native and exotic trees. Water channels run throughout the grounds and shape the layout of the pathways and planted areas.

The castle garden was founded at the end of the 16th century by Peter Vok of Rosenberg, who moved the road through the Břilice gate and had the wetland between today's Sokolská street and the castle wing filled with soil. Vegetables were grown there alongside ornamental plants, and a large painted wooden lusthaus stood on the site. After the imperial garrison occupied Třeboň in 1623 the pavilion was used to store fishing nets and eventually burned down; the Schwarzenbergs began restoring the garden in the 1670s. In 1804 a large collection of trees was planted, giving the grounds their English landscape park form.

The park is a popular spot for wedding ceremonies, held mainly in the castle pavilion and the Schwarzenberg Hall of the castle. In the eastern part next to the castle are fountains and seating areas. The pavilion hosted Dušák's band during interwar economic exhibitions, and President Tomáš Garrigue Masaryk visited the park in June 1925.

The park is fenced and closes for the night. Entrances are from the north on Sokolská Street, from the west over a small bridge by the town library, and from the east through the castle. The grounds were flooded in 2002 and renovated in 2019 and 2020, when the furniture was renewed.

At the castle courtyard entrance stands an unusual maple tree with two trunks growing from a single base. Near the outlet of Svět pond grows a white willow of remarkable size that stands out from other trees in the grounds.
