He was knighted

A well-known fact about Christopher Wren is that he was knighted in November 1673 for his outstanding architectural creations and the significant contribution he made to reconstructing the city of London after the Great Fire. This honor was given to him after he departed from the Savilian chair in Oxford, at which point he had already started to establish himself as a notable architect by serving the Crown and helping to rebuild London following the Great Fire.

He also engaged in enough public affairs to be re-elected as a member of parliament four times. In 1667, Wren ran for office in a by-election for the Cambridge University constituency, where Sir Charles Wheler defeated him by six votes. In a by-election for the Oxford University constituency in 1674, he lost to Thomas Thynne and failed once again. In his third effort, Wren was successful, and from 1685 to 1687, he served as a member of the Loyal Parliament representing Plympton Erle. Wren was elected to represent New Windsor in the general election on January 11, 1689, but his election was invalidated on May 14, 1689. On 6 March 1690, he was chosen to serve as mayor of New Windsor, however, on 17 May 1690, this election was ruled invalid. At the general election in November 1701, he was chosen without opposition for Weymouth and Melcombe Regis more than ten years later. The following year's general election marked his retirement.
