Mugdock Castle on Sullivan's Island, South Carolina is a striking coastal landmark combining multiple architectural styles on the island's quiet western end near Charleston. The property encompasses the original Gothic-style Winter Hall built in 1830, which originally served as an Episcopal Church and chapel for Fort Moultrie soldiers, alongside the Romanesque-style Summer Hall constructed in 2009. This 4,950-square-foot residence features six bedrooms, five bathrooms, and includes a swimming pool. The castle's unique blend of 19th-century religious architecture and modern coastal design creates one of Sullivan's Island's most iconic and distinctive properties.
