Kastellet

It was initially dispatched by Frederik III in 1662. Today, it is a standout amongst the most verifiably suggestive destinations in the city, its lush bulwarks and canal encompassing some lovely eighteenth-century sleeping enclosure, and additionally a sanctuary at times utilized for shows.
On the bulwarks is a noteworthy windmill, and you get some fantastic perspectives of the harbor and Marmorkirken's Vatican-like dome. Just past the fortification's southeastern edge is Anders Bundgaard's great Gefion Fountain, portraying the Norse goddess Gefion guiding some somewhat stoic bulls. Tourists come here from all over the world with their family members and friends and enjoy this place.
