Hagaparken ("Haga Park"), or simply Haga in Solna Municipality just north of Stockholm, Sweden is a vast and popular nature area, with large parks, lakes, woods and gardens. Within the park is Haga Palace, King Gustav III's Pavilion, the Chinese Pavilion, the Echo Temple, the Turkish Kiosk, an older castle ruin (which is not really a ruin as it is the remains of a castle never finished) and several other interesting buildings on the grounds (such as the peculiar Copper Tents and also the Butterfly House).
