London – After fifteen years and £40 million ($65 million), a massive restoration of St. Paul’s Cathedral in London is finally finished. The timing is perfect because it coincides with the 300th anniversary of the cathedral’s original completion. In de­si­gning Saint Paul’s Ca­the­dral, English ar­chi­tect Chris­to­pher Wren, also known as a sci­en­tist and ma­the­ma­ti­cian, was hea­vily in­flu­en­ced by the style known as ba­ro­que ar­chi­tec­ture, pre­viously un­k­nown to Eng­land.
