Tryon Palace says a proposed Senate budget would force its closure next year.
The historic location in New Bern, site of the state's first capitol, sees more than 140,000 visitors each year.
The Palace says if the Senate plan is passed its newly opened North Carolina History Center would possibly have to shut down in July due to a 36% cut in state funding. The two-year budget proposal would then slice 89% of state funding to the site for the next year, forcing it to close on or before July 1, 2012, according to the Palace.
The Senate is expected to vote on the budget next week.
