History buffs put on a birthday party for the architect behind the century-old Minnesota Capitol.

Saturday’s event was staged by the Cass Gilbert Society and the State Capitol Historic Site. Gilbert’s actual birthday falls on Nov. 24. He died in 1934.

Organizers served cake and set up an exhibit featuring Gilbert’s work. The exhibit will be on display through the end of November.

During his storied career, Gilbert also designed the U.S. Supreme Court building, the Woolworth Building skyscraper in New York and state capitols in Arkansas and West Virginia.
