About
Where History Meets Its Next Chapter
Welcome to Antithesis
Long before it became Antithesis, these walls were filled with celebration. In 1884, prominent Colorado businessman, Lyman Robison, built this extraordinary mansion as a home for family, friendship, and gracious hospitality. For generations, guests gathered here to celebrate milestones, share remarkable dining, and create memories that would outlive them. More than 140 years later, the purpose of this house remains unchanged.
Today, Antithesis honors that legacy—not by preserving it behind velvet ropes, but by bringing it back to life. Every dinner, every toast, every wedding, every anniversary, and every conversation adds another chapter to the story that began over a century ago.
Today, historic architecture meets modern culinary artistry. Timeless elegance meets bold creativity. Past and future exist together under one roof. Because the greatest historic buildings aren’t meant to be admired from a distance. They’re meant to be lived in.
Welcome to the next chapter of the Historic Robison Mansion. Welcome to Antithesis.
