Located in the heart of downtown St. Paul, overlooking Rice Park and only a moment away from the Mississippi River, Avalon is housed within the former James J. Hill Reference Library. This Renaissance Revival building, completed in 1916, was originally established as a living gift from railroad magnate James J. Hill and his family to support business research and economic development in the region. Designed by architect Electus D. Litchfield, the structure features a grand three-story reading room, soaring stone pillars and Tennessee marble throughout.

For nearly a century, the Hill Library served as a vital resource for entrepreneurs, researchers, and the public. In 2021, Minneapolis-based developer First & First acquired the building with a vision to repurpose it as a dynamic event space. Renovations commenced in Spring of 2025 to transform the historic library into Avalon, an event center aiming to preserve the building’s architectural integrity while adapting it for modern use.

Today, Avalon stands as a testament to St. Paul's rich history and commitment to innovation. The venue offers a unique blend of historic charm and contemporary amenities, making it an ideal setting for weddings, corporate events, and cultural gatherings. By revitalizing this iconic landmark, Avalon continues the legacy of James J. Hill, fostering community engagement and economic growth in the heart of St. Paul.
