Looking up from the middle of St. Paul’s is this impressive dome. With this wide angle lens you can see the eight arches which support the huge dome. From the inside the dome measures 31 metres (or 102 feet) across. The cathedral was designed by Sir Christopher Wren and built in 1697. The dome was painted and decorated by Sir James Thornhill. It shows eight scenes from the life of St Paul, set in illusionistic architecture. This creates the illusion of real architectural features.
