The hamlet of St Anthony-in-Roseland lies on an inlet of the Percuil River, directly across the water from St Mawes, from where it can be reached by a pedestrian ferry during the summer months. The restored church, which is owned by the Churches Conservation Trust, is one of the best early English churches in Cornwall, a good example of what a 12th or 13th century church would have looked like. Place House, the neo-gothic building which stands so close to the church as to almost hide it from view, was built in 1840. The house stands on the site of a Celtic monastery and incorporates the old refectory which was linked to the church by a passage.
A coastal footpath connects St Anthony church with St Anthony head, approximately one mile away, the site of a fort which overlooked Falmouth harbour. During World War I the area was used as an army training ground, and in World War II gun batteries were stationed here. The heavy fortifications still remain and provide a marvellous vantage point overlooking the English Channel and the entrance to Falmouth Bay. St Anthony Head is owned by the National Trust, and car parking and toilet facilities are provided at the site.
In 1834, St Anthony lighthouse was built at the foot of the cliffs.
