A landmark's last weekend
The Smithsonian's second-oldest building is closing again. Its last weekend comes with a free circus
The three-day program is both a finale and a promise that the building's story is not finished. Admission is free and the announced events require no registration.

The final public weekend before the Smithsonian's Arts and Industries Building closes September 7 will not be quiet. Aerial artists, jugglers, rigging demonstrations, costume work and a life-sized circus-science machine are scheduled to fill the building from September 5 through 7. Admission is free. Registration is not required.
The farewell runs for three full days
The Smithsonian says the program will run from 10 a.m. to 6 p.m. on Saturday, Sunday and Labor Day. It is designed as a drop-in weekend, so visitors can move among performances, demonstrations and hands-on activities without booking a timed reservation.
The lineup turns the building itself into part of the show. Aerial work depends on the room above the performer. Rigging makes the hidden engineering visible. Costume and juggling sessions bring the labor of circus-making down to eye level.
Schedules can change, especially across a live three-day program. Anyone making the trip should check the official Smithsonian listing again before leaving home.
The building has always been a stage for big ideas
The Arts and Industries Building opened in 1881 and is the Smithsonian's second-oldest building on the National Mall. Its long history includes national exhibitions, new technologies and public spectacles, which makes a circus-science finale feel unusually well matched to the room.
The weekend is not being presented as a permanent goodbye. The Smithsonian describes the September 7 closure as part of a broader transition involving the Arts and Industries Building and the Castle.

The acts come with the mechanics exposed
The official program pairs performance with explanation. Visitors are expected to see aerial-rigging and costume-making demonstrations, plus explanations of how pulleys lift weight and how a teeterboard transfers energy.
A life-sized circus-science machine gives the weekend a centerpiece built for the room. The value is not only seeing a finished trick. It is seeing the practical decisions that let the trick happen.
A closing date gives the weekend its tension
Most museum programs ask visitors to come see what has opened. This one asks them to arrive before the doors close again. That changes a free holiday-weekend event into a last chance to experience the building while it is active and full.
The circus ends at 6 p.m. September 7 under the current schedule. The next chapter for the building will take longer. For three days, at least, the old exhibition hall gets one more crowd looking up.
