Charles Fort
Built---almost symbolically---on the site of the ruins of an earlier Irish castle, Charles Fort on the east side of the Bandon River estuary in the late 17th century was constructed by the British after they defeated the Spanish and Irish forces. One of Europe's best-preserved "star forts" encloses some 12 clifftop acres and is similar to Fort Ticonderoga in New York State. If the sun is shining, take the footpath from Kinsale signposted Scilly Walk; it winds along the harbor's edge under tall trees and then through the village of Summer Cove.
