BOCA RATON, FL (Boca Post) (Copyright © 2025) — Friends, colleagues, and community leaders gathered at The Boca Raton on Monday night to celebrate the retirement of Mary Csar, the longtime leader of the Boca Raton Historical Society & The Schmidt Boca Raton History Museum.

The evening doubled as a milestone for the resort itself. The Boca Raton used the occasion to mark the opening of the Cloister Inn Museum, a new on-site exhibit created to commemorate the property’s upcoming centennial in 2026.

It was a night where Boca’s local history and its hospitality brand crossed paths in the same room, with speakers returning again and again to a simple point: Csar helped make the city’s history visible, accessible, and worth protecting.

The retirement celebration honored what organizers described as Csar’s decades-long dedication to preserving Boca Raton’s history, and to strengthening partnerships across the city. That work, they said, wasn’t limited to museum walls. It was about building connections and keeping Boca’s story intact as the city keeps changing.

The newly unveiled Cloister Inn Museum exhibit is designed as a permanent installation at The Boca Raton. It highlights the resort’s architectural legacy and offers visitors a look back at the hotel’s past as it approaches 100 years.

The exhibit’s debut also carried a broader message for the crowd: this is a centennial year coming up, but it is also a reminder that Boca’s identity is made in pieces — historic preservation, cultural programming, and the institutions that keep records, artifacts, and stories from slipping away.

As part of the program, Csar formally passed the torch to incoming Executive Director Olivia Hollaus.

In remarks during the event, Csar expressed confidence in Hollaus and in the museum’s future leadership and vision, framing the transition as a continuation rather than an ending. She’s retiring from the role, but the work moves forward, with new hands now holding the day-to-day.

City leaders made the recognition official.

Deputy Mayor Fran Nachlas and City Council members Yvette Drucker, Andy Thompson, and Marc Wigder presented Csar with the Key to the City, honoring her leadership, preservation efforts, and what they described as her lasting impact on Boca Raton’s cultural legacy.

The presentation landed as the emotional center of the night — the formal acknowledgment after years of meetings, programming, fundraising, community outreach, and the less visible work of keeping a historical institution steady.

The setting mattered, too. Holding the celebration at The Boca Raton — alongside the opening of a centennial-focused exhibit — underscored the theme of the evening: history isn’t just something filed away. In Boca, it shows up in architecture, in civic life, and in the institutions that decide what gets remembered.

Organizers described the night as both a tribute and a forward-looking moment, celebrating Boca Raton’s past while setting the stage for milestone anniversaries ahead. That includes the resort’s centennial in 2026, and continued cultural programming intended to connect local history to national narratives.

For the people in the room, it was also simpler than that.

A retirement, a packed crowd, a new exhibit opening its doors, and a longtime local leader receiving one of the city’s highest honors — all in the same evening, in the same place.
