365 Thames St museum vestibule

The project architect argued the glass infill preserves the arches' prominence by receding, is reversible, and gains the museum usable, accessible space.

The Historical Society's director noted its 30-year city lease, the $2.5 million it is raising, the existing glass and damage being repaired, and the planned December 31, 2026 opening.

The museum's exhibit designer said the vestibule is essential for front-door ADA access and a welcoming, accredited museum experience.
