The dome reaches a height of 111 meters and weights about 66,000 ton. Eight arches support the dome. On top of the dome is a large lantern with a weight of 850 ton.
教堂的穹顶高达111米，重达66000吨，由八座拱桥支撑。穹顶冠以一个重达850吨的巨型灯笼式天窗。
560 Steps lead visitors along three galleries all the way to the top of the dome. The first gallery, the Whispering Gallery, just inside the dome, is renowned for its acoustics . The second gallery, the Stone Gallery, is situated at a height of 53 meter on the outside of the dome, right above the colonnade . On top of the dome, at a height of 85 meter, is the narrow Golden Gallery, which encircles the lantern's base. From here you have a magnificent view over the City.
游客要登上560个台阶，穿过三个画廊才能到达穹顶顶端。第一个画廊，回音廊，就在穹顶的里面，以它的回声效果著名。第二个画廊，石廊，坐落于穹顶外面53米高处，就在柱廊的上方。在穹顶的上端，85米高处，是窄长的金廊，环绕着灯笼式天窗的底部。在那里你能看到非常壮观的伦敦市景色。
The Baroque interior is just as imposing as the exterior of the church. The mosaics on the ceiling were added in 1890 by William Richmond after Queen Victoria complained that there was not enough color in the cathedral. The baldachin above the altar was rebuilt in 1958 after it was damaged by bombardments during World War II. The only monument in the church that survived the fire of 1666 is the tomb of John Donne, from 1631.
教堂巴洛克式的内部结构与其外部结构一样宏伟。1890年，维多利亚女王抱怨教堂内色彩不足，之后威廉·里士满便在天花板上添加了马赛克图案。祭坛上方的华盖是在1958年重建的，它曾被第二次世界大战的炮弹击毁。教堂内唯一躲过1666年大火的历史遗迹是约翰·邓恩的坟墓，于1631年所建。
The church was the site of a number of important historic events such as the funeral of Admiral Nelson in 1806 and the funeral of Winston Churchill in 1965. Prince Charles and Lady Diana Spencer married here in 1981.
圣保罗大教堂是很多重要历史事件发生的地方，比如1806年海军上将纳尔逊的葬礼，以及1965年温斯顿·丘吉尔的葬礼。1981年查尔斯王子和戴安娜王妃也是在这里举行的婚礼。
