After a months-long closure, The National Gallery of Art’s East Building will reopen on June 30, the museum announced on Wednesday.

The building closed initially on Feb. 28 this year, as crews finished replacing the iconic atrium skylight for the first time since its original installation in 1978 — one of the major renovation projects the NGA is undertaking. According to an NGA press release, the new glass panes make the space appear brighter, restoring the light to levels seen when the building first opened. To complete the renovation, crews installed an elaborate system of sliding platforms, replacing the triangular glass panels.

The building will also boast several accessibility upgrades when it reopens later this month. New double doors were added at the main entrance, and ADA-compliant bathrooms have been installed on the ground floor, per the release. The existing bathrooms on the mezzanine level were also renovated, and a lactation room will be available near the auditorium later this summer.

Within a month of reopening, the East Building is slated to host two new exhibits: The Woman in White: Joanna Hifferman and James McNeil Whistler will open on July 3, and The Double: Identity and Difference in Art since 1900 (which was postponed due to the renovation), will open on July 10.

Alexander Calder’s mobile, which was removed in summer 2020, will be reinstalled this fall, and the protective enclosures constructed around other large sculptures in the atrium will come down for the reopening later this month.

Meanwhile, the West Building is in the midst of its own series of projects through at least spring 2024, closing one quadrant of the building for around six months at a time. (From June 2022 through early 2023, the southwest quadrant of the main floor is off-view.) The construction is repairing stone on the West Building exterior, replacing select roofing areas, and making improvements to doors.
