The original wooden structure was destroyed in the Great Fire of London in 1666. Construction of this new, grander, building started in 1675 and was finally completed in 1708. DEsigned by Sir Christopher Wren, it was the first "English" cathedral to be built following the Reformation of the mid-16th century.
@jackie8 Thank you, Jackie. I actually meant to take a completely different photo but the circumstances didn't work out, so this was very last minute!!!
