Smithsonian Castle is Open

The Castle is the Smithsonian’s first home and its symbolic heart. Located on the south side of the National Mall in downtown Washington, D.C., the building today symbolizes the Smithsonian and is its most recognized, built artifact on the Mall.

The Castle closed February 1, 2023, for its first major renovation in more than 50 years. All elements of the building are undergoing extensive renovation—with a pause in renovation for the nation's 250th anniversary summer 2026
Lets start our first event with a simple, yet iconic, trip of getting to actually look into the castle. I'll be out front with a MeetUp sign Celebrating USA 250. Please sign up if you're planning to attend with us, most museums have limits to group sizes.
