MoMath's New Home: Math, Exhibits, and an Art Gallery

The National Museum of Mathematics (MoMath) has relocated to a permanent site at 635 Sixth Avenue in Manhattan, occupying a lease of 34,363 square feet that is nearly double the size of its original gallery on East 26th Street. The expanded footprint gives the museum room for additional classrooms, interactive installations, and a state-of-the-art presentation area, and it will allow MoMath to host larger public events and school groups than before.

Composite, the museum’s dedicated gallery for work at the intersection of mathematics and art, opened with an inaugural reception on February 6, 2026, and will present rotating exhibitions that translate mathematical ideas into visual and sculptural forms. Visitors will encounter installations that combine light, sound, and geometry, as well as solo shows that explore curves, symmetry, and pattern; the gallery is intended to spotlight artists who use mathematical models in their practice.

While MoMath operated a temporary pop-up at 225 Fifth Avenue during the transition, the new Chelsea address benefits from large windows and higher ceilings, features noted by designers and local coverage. The building’s renovation, guided by exhibit planners and architects, includes classrooms for early learners and event spaces that can accommodate seated dinners for 300 guests, expanding the museum’s programmatic possibilities.

The museum is open seven days a week from 10:00 am to 5:00 pm, and it has combined legacy favorites with dozens of new exhibits so that families, students, and enthusiasts may engage with mathematics in hands-on ways. If interest grows, the museum will be well positioned to deepen its outreach and host more community programs.
