Sankt Annæ Plads is a public square which marks the border between the Nyhavn area and Frederiksstaden neighborhoods of central Copenhagen, Denmark. It is a long narrow rectangle which extends inland from the waterfront, at a point just north of the Royal Danish Playhouse at the base of the Kvæsthus Pier, now known as Ofelia Plads, until it meets Bredgade. A major renovation of the square was completed in 2016.The Garrison Church is located on the south side of the square. Amaliegade, one of the two axes on which Frederiksstaden is centered, extends from the square.
