The Weir Farm National Historic Site at 735 Nod Hill Road in Wilton is closed due to the federal government shutdown that began Saturday, Dec. 22, at 12:01 a.m. The Weir Farm National Historic Site is the only National Park Service site dedicated to American painting. The Weir House, Weir Studio, Young Studio, and Visitor Center on the 68-acre site have already closed for the off-season. As part of the government shutdown-induced closing, Weir Farm's website will not be updated and, as a result, "may not reflect current conditions," according to a message on Weir Farm's website. There is no set date for when the government shutdown will end.
