The Minnesota State Capitol is one of the finest beaux-arts public buildings in America, completed in 1905 to a design by Cass Gilbert — who later designed the US Supreme Court building and New York's Woolworth Building. The dome, larger than the US Capitol's, rises above St. Paul's skyline and is visible from miles away. Free guided tours cover the legislative chambers, the restored governor's reception room, and the extraordinary rotunda beneath the dome.
The building underwent a five-year restoration completed in 2017, which returned the interior to its original grandeur. The Rathskeller Cafe in the basement — a restored German-style dining hall — is a genuine historical curiosity, still serving lunch on weekdays in a 115-year-old space. Worth visiting even if state politics leaves you cold.
