Thousands wander across Hampstead Heath's wild and undulating parkland every year, but very few discover this eerie and elegant pocket of faded grandeur on the West Heath. Built by Lord Leverhulme at the start of the twentieth century as a setting for his extravagant parties, it includes impressive gardens and a dramatic elevated walkway, where overhanging plants create a lush canopy and tangled roots twist around smooth stone columns. A little window into the world of the Edwardian super-rich.
INSIDER TIP: Visit in the early evening and you might catch a glimpse of the long-eared bats which roost here.
