Tucked away down a cobbled alley behind Russell Square Station, The Horse Hospital, a converted stable, is a unique and totally independent arts space specialising in underground and experimental media. The gallery space itself (known as The Chamber of Pop Culture) houses unusual exhibitions, film screenings and other events.
London has great green spaces. There are large royal parks and small public gardens, hidden allotments and roof terraces. Each one has its own identity and characteristics and everyone has their favourite. In summer they become extensions of people homes, you see girls sunbathing from 9 am and the endless picnics mean you can eat 3 meals a day in the park. My favourites - St James Piccadilly Gardens, Hyde Park, Barbican Conservatory.
This uninspiring sounding place is a disused railway line that runs along the roofline from Finsbury Park to Highgate. A great place to excerise and escape.
