Wren left for Paris in July 1665 on his first and only trip abroad. In France, the architect encountered an architectural milieu more closely linked to the ideals of the Italian Renaissance. Wren also met Gian Lorenzo Bernini, who was \"widely acknowledged by contemporaries as the greatest artist of the century\". Though Bernini's concrete influence on Wren's designs was transmitted via published plans and engravings, the encounter surely impacted the budding architect and his vocational trajectory.
St Paul's Cathedral in London has always been the highlight of Wren's reputation. His association with it spans his whole architectural career, including the 36 years between the start of the new building and the declaration by parliament of its completion in 1711.Letters document Wren's involvement in St Paul as early as 1661, when he was consulted by Charles II regarding repairs to the medieval structure. In the spring of 1666, he made his first design for a dome for St Paul's. It was accepted in principle on 27 August 1666. One week later, however, the Great Fire of London reduced two-thirds of the City to a smoking desert and old St Paul's to ruin. Wren was most likely at Oxford at the time, but the news, so fantastically relevant to his future, drew him at once to London. Between 5 and 11 September, he ascertained the precise area of devastation, worked out a plan for rebuilding the City and submitted it to Charles II. Others also submitted plans. However, no new plan proceeded any further than the paper on which it was drawn. A Rebuilding of London Act which provided rebuilding of some essential buildings was passed in 1666. In 1669, the King's Surveyor of Works died and Wren was promptly installed. 153554b96e
