Sadová kolonáda, 19th-century colonnade in Karlovy Vary, Czech Republic.

Sadová Colonnade is a 19th-century cast-iron colonnade in Dvořákovy sady gardens featuring connected arcades with classical architectural details. The structure creates covered walkways and spans through the park with a series of interconnected sections.

Built between 1880 and 1881 by architects Fellner and Helmer, the colonnade was constructed during Karlovy Vary's rise as a European spa resort. The structure reflects the city's efforts to expand its facilities for wealthy spa visitors during this period.

The colonnade is used for drinking from the Sadový pramen, though the spring's outlet lies in the Vojenská lázeňská zotavovna. Since 10 July 2004 the western pavilion has served the Hadí pramen, discovered in the late 1980s by the spa hydrogeologist Vylita; at 30 °C it is counted among the cooler springs and considered the tastiest in Karlovy Vary.

The covered walkways offer shelter from the weather as visitors explore the park and nearby mineral springs. The site is open and accessible, making it easy to stroll through at your own pace.

The colonnade's cast-iron parts were made at the Mariánská huť ironworks of Prince Salm in Blansko. Until 2004 the structure had never been repaired, only repainted twelve times; damaged and missing pieces were then restored, the stone base repaired and the roof covered with new slate.
