The municipality and borough of the City of London, known by some as the “Square Mile” for its density, is the historic and financial core of Greater London. The corresponding area maintains its origins as a center for trade, dating back over 2000 years when it was conquered as a Roman colony. London also has a history as a strong economic center through the banking, finance, newspaper and legal industries.
“The City” extends along the north side of the Thames River from the west at Temple Church, built in the 12th-century by Knights Templar; past St. Paul’s Cathedral, designed and built by Sir Christopher Wren after the Great Fire of 1666 (the 5th iteration since the 7th-century original); also past the Monument to the Great Fire, a column also designed by Wren; to the Tower of London on the east end, established in 1066 by William the Conqueror who built the White Tower. Other points of interest are the Museum of London and the original London Wall, built by the Romans.
