Continue walking east on State Street to Jackson Street, then turn south (right) on Jackson. Walk one block, crossing Kilbourn Avenue, where you'll find Cathedral Square Park.

Originally known as Courthouse Square, the land was donated by city founder Solomon Juneau in 1836. It originally housed a court house and jail. In 1854, a mob of 5,000 people converged at the jail to rescue Joshua Glover, a runaway slave captured and imprisoned by federal marshals. This area was also used to assemble troops who were heading to or returning from the front during the American Civil War. The jail was moved to another site in 1886, and the courthouse was used until 1931 when the current Milwaukee County Courthouse was built.

The area became a park in 1939 and is named after Cathedral of St. John the Evangelist, which sits across the street. (The park is not owned by the church.) Today, Cathedral Square is a popular local park and home to numerous festivals, including Jazz in the Park, Bastille Days, Cathedral Square Farmers Market, the Holiday Lights Festival and many others.

The Cathedral of St. John the Evangelist, completed in 1852, is part of the Catholic Archdiocese of Milwaukee. The Cathedral is on the National Register of Historic Places and is a designated Milwaukee Landmark.

The building's architect was Victor Schulte, and it is designed in the nineteenth-century Zopfstil style. Schulte used Cream City brick in the construction, a distinct light colored brick made from clay found around the Milwaukee area.

If the Cathedral is open, step inside. The Cathedral of St. John features thirteen large hand-cut stained glass windows made by the T.C. Esser Company of Milwaukee. The center of the sanctuary also contains a large baptismal pool and marble font.

When you're ready to move on, begin walking south on Jackson Street.
