Patriots Point will make a major announcement about the strategic development of some of the 367 acres it owns in Mount Pleasant.

The announcement will be made at 11:15 a.m. Wednesday on the World War II-era aircraft carrier Yorktown, the centerpiece attraction at the tourist site on Charleston Harbor.

“This project, the most significant decision to come from Patriots Point in decades, will have a lasting economic impact on Charleston and the state of South Carolina,” Patriots Point said in a statement.

The naval and maritime museum has been working for months to put together a plan to develop 36 acres around its ticket office.

Plans have called for a new museum, hotel, visitors center, gift shop and restaurants.
