Saya mau tau Exterior dari Katedral St Paul. Jelaskan dalam bahasa melayu

The most notable exterior feature is the dome, which rises  to the cross at its summit, and dominates views of the City. The height of 365 feet is explained by Wren's interest in astronomy. Until the late 20th century St Paul's was the tallest building on the City skyline, designed  to be seen surrounded by the delicate spires of Wren's other city churches. The dome is described by Sir Banister Fletcher as "probably the finest in Europe", by Helen Gardner as "majestic", and by Sir Nikolaus Pevsner as "one of the most perfect in the world". Sir John Summerson said that Englishmen and "even some foreigners" consider it to be without equal.
