The London Coliseum is home to the ENO (English National Opera) and the English National Ballet. With almost 2500 seats, it's one of the largest theaters in London. The interior is beautiful and mildly ornate, bedecked in pale blue and gold, and the scenery on stage is always minimal but effective. The Coliseum is centrally located, situated between Trafalgar Square and Leicester Square, and is hard to miss with its trademark cupola. For fans of the ballet or opera, a performance here is a must-see attraction while visiting London.
