Arriving just before the building closed at 5pm, I just missed popping in to see the interior which from online photos appeared compact though quite impressive with its candy-colored chinoiserie paintings, restrained floral flourishes trimmed with gold, and a small though beautiful cupola.
Also built by Frederick the Great, this functioned as a fantastical intimate tea house designed in a Rococo fashion, demonstrating Chinoiserie stylistic choices that were popular among the 18th century European courts. It's interesting to see the interpretation of what Prussians imagined China to be like, as the wording on the SPSG* website alludes to: "it shows less of China as it was back then than it does of European's ideas about it."
The outside of the pavilion is encircled with gilded figures of musicians and tea drinkers, columns shaped like palm trees and a tassel-edged roof.
Like some of the other buildings in Sanssouci Park, it's closed during winter months and opens seasonally in the warmer ones. Normally tickets are €5 though included with the Sanssouci+ ticket or other combo tickets. It's located fairly close to the southeast edge of the park, and requires a walk to reach, not accessible by car though you can park outside the park and walk over in about 15-20 min.
