In celebration of the 110th anniversary of the Riordan Mansion's completion, enjoy a fresh take on the unique home's origins and features. This exploration may just leave you seeing our architectural treasure with new eyes! As a tribute to 1904, special treats from the St. Louis World's Fair will be provided. Bring your lunch and dessert is on us! Shared by Richard Patton, Riordan Mansion volunteer researching the Riordans' correspondence.
