Westminster Abbey in London is a UNESCO World Heritage Site. In and around Trafalgar Square, The 18ft high statue of Nelson sits on 151ft of granite. The column was built between 1840 and 1843 to commemorate Admiral Horatio Nelson's death at the Battle of Trafalgar in 1805. The English Chamber Orchestra gets it's name from Trafalgar Square's St Martin-in-the-Fields church, in which its first concert was performed. For all you classical music fans, this is where Sir Neville Marriner started! Copyleft music by Rogg Maddeford Duo. More than a day trip from Thornbury Castle, and certainly worth the travel!
