This is so called Grotto - a rather small pavilion residing by tiny pond in Kuskovo estate. Build in 1756-1761, it was used for exqisite entertainments and delicate rest during hot summer days. Decorated with real shells, mirrows and sea stones, the Grotto imitates a natural cave providing pleasures for body and mind.
In 1939 Kuskovo was turned into Ceramics Museum, and today you can see beuatiful pieces of china ware and figurines exhibited in the Grotto pavolion.
By the way, the weather is nasty in Moscow: the temperature is only +6C and it's been raining since Wednesday. Still waiting for the summer...
