AddressHarmondsworth Moor, 41 Moor Lane
The open parkland contains a variety of habits including meadows, rivers, lakes and ponds. Meandering paths take you through open countryside and new plantations. Harmondsworth Barn is worth the visit while you are in the area. Rescued by English Heritage after years of neglect, this Grade I listed barn ranks alongside the Houses of Parliament and Westminster Abbey for its exceptional architectural and historic interest. It was dubbed the “Cathedral of Middlesex” by Sir John Betjeman.
