It paces a Londoner's life. When the tide is low I like wandering on the "beach" and discovering tunnels that take me to the centre of the Earth.

Architecture collective Assemble has transformed a former public swimming pool to create a new art centre for Goldsmiths college. The baths were closed to public in 1999. The space now accommodated seven new gallery spaces, a cafe and event space. 

Eccentric and surprising house and museum of architect Sir John Soane. Mostly unchanged since his death over 180 years ago, it is full of atmosphere. Also have spotlit, late night openings.  

Free natural ponds, open all year round (check online for varying opening hours according to seasons). Get an absolute get away feeling right in the heart of London, a treat if you enjoy swimming with ducks. Amazing park to enjoy a few games of cards and a walk around afterward too...
