Buckingham Palace
Located in Westminster- where many famous landmarks are situated- Buckingham Palace is the official residence and administrative office in London of the reigning British monarch. At most times, it is the centre of state occasions, as well as royal events and hospitality. It was originally built as a large townhouse called Buckingham House in 1703 and was significantly enlarged and turned into a neoclassical style palace on the accession of Queen Victoria in 1837. It has 775 rooms, including state rooms, with the largest private garden in London. The famous front balcony is where the Royal Family normally greets the crowd.
***Note: after a visit to Buckingham Palace, an option is to continue down to The Mall or Trafalgar Square, or venture on to Kensington Palace and Hyde Park.
