What is the name of London's tallest building until 1962, known for its large dome designed by Sir Christopher Wren?

The name of London's tallest building until 1962, characterized by its distinct large dome designed by Sir Christopher Wren, is St. Paul's Cathedral. This iconic structure, completed in the early 18th century, became a significant landmark in London and was an engineering marvel of its time. The dome stands out in the city’s skyline, symbolizing resilience, especially after surviving the Blitz during World War II. Its architectural design reflects the Baroque style, making it not only a place of worship but also a historical and cultural symbol for London.

Westminster Abbey, while also an important architectural site, is not known for having the large dome associated with Sir Christopher Wren. The Shard, completed much later, has since become a recognizable feature of London's skyline but did not exist before 1962. Big Ben refers specifically to the clock tower and its bell rather than a building and thus does not pertain to the context of the tallest building at the time.
