Žižkovy sady is a park in Hradec Králové, Czech Republic, designed by František Thomayer between 1905 and 1907. It features French-style ornamental gardens with a central circular fountain and elevated flower beds adorned with seasonal plantings. The park borders the Old Town's terraces to the south and Československé armády Street to the north, integrating it into the city's urban landscape.

The establishment of Žižkovy sady marked a significant transformation in Hradec Králové. Originally, this area housed a military riding school known as "Pod Pekhausem." The park was developed on the initiative of a local beautification society and named after Žižkový náměstí, designated since 1896. This change reflects broader trends during the early 20th century when Czech lands were part of Austria-Hungary, experiencing cultural and political shifts leading up to World War I.

Architecturally, František Thomayer's design incorporated elements typical of French ornamental gardens. The park includes a central circular fountain surrounded by a grassy parterre, with elevated flower beds on both the west and east sides filled with seasonal plantings. Despite initial delays due to weather conditions, such as a storm in April 1905 that temporarily halted construction efforts, significant planting activities continued into 1906. The city council approved financial accounts for planting grass seed, trees, shrubs, and flowers, underscoring the community's commitment to creating this urban green space.

Throughout its history, Žižkovy sady has witnessed various developments and enhancements. By 1908, despite initial criticism for slow progress, it became a well-regarded example of modern flower gardens. A notable tradition began with colorful algae donated from a botanical garden in Zagreb to decorate the park's pond, adding to its aesthetic appeal. This practice continued over subsequent decades, contributing to the park's unique charm.

Today, Žižkovy sady remains an accessible and cherished part of Hradec Králové. Visitors can explore its well-maintained gardens, admire the central fountain, and view monuments such as the one dedicated to Jan Žižka from 1971 and another honoring L. J. Pospíšil from 1933. The park's historical significance and beautiful design make it a worthwhile destination for those interested in both nature and history.

Žižkovy sady stands as a testament to early 20th-century urban development and beautification efforts, offering visitors a glimpse into the past while providing a serene environment for relaxation and reflection. Its enduring appeal invites locals and tourists alike to experience its historical and aesthetic value firsthand.
