The Temple of Echo, Neoclassical temple in Hagaparken, Stockholm, Sweden.

The Temple of Echo is an open oval pavilion on a small hill just east of Gustav III's Pavilion in Hagaparken, Solna. Its 24 painted wooden pilasters rest on 12 wooden pedestals with sandstone slabs, with painted latticework between them, and the whole is covered by a copper roof. It was designed as a summer dining room, with a large oval table made specially for the room.

Built in 1790 on a small hill east of Gustav III's pavilion, the temple was designed by Carl Christoffer Gjörwell under Louis Jean Desprez. It was restored in 1846 by Axel Nyström, who added ceiling paintings of cupids and birds and a decorative frieze. Ragnar Hjorth's 1924 restoration painted over the frieze, and the 1992–93 work recreated Nyström's decoration.

The building was originally called the Green Salon and only later became known as the Echo Temple, because a voice spoken under its vaulted roof returns as an echo. Gustav III had a large oval dining table made specially for the room and placed in its centre.

The site sits within Hagaparken and is accessible via several walking paths marked throughout the park. The grounds remain open year-round, though summer months offer more frequent events and guided visits that can enhance your understanding of the space.

The circular design creates an acoustic phenomenon where whispered sounds at one point can be heard clearly from another spot across the interior. This effect was intentional in the design and gives the space a playful quality that goes beyond its formal appearance.
