St Tugual's Chapel, 11th-century chapel in Herm, Channel Islands

St Tugual's Chapel is a small stone building on Herm, the smallest Channel Island open to the public. Its rough grey and brown stone facade has a round-arched doorway with a glazed upper section and two small barred windows. A low-pitched roof of reddish-brown tiles covers the chapel, and a gravestone stands on the grass in front.

The chapel incorporates an earlier structure and dates from the 11th century; the site may have held religious importance since the 6th century. It was built by Norman monks living on Herm. The Wood family, who took over the island's lease in 1949, reopened parts of the chapel and cleared several windows. Restoration in 2010 and 2011 included re-roofing, repointing, re-rendering and drainage, and the chapel reopened with a re-dedication service in May 2011.

The chapel is non-denominational and not consecrated, and it is dedicated to Tugdual of Tréguier. It is uncertain whether the name comes from a visit by the saint to Herm or from his followers. The States of Guernsey are responsible for its upkeep, and it reopened with a re-dedication service in May 2011.

The chapel is accessible on foot from Herm village and offers views across the island's northern coast. Wear sturdy shoes as the path can be uneven, and weather conditions change quickly in this coastal location.

Archaeological digs near the chapel uncovered ancient human remains from the 10th century, offering clues about early burial practices on the island. These findings show the site served as a burial ground long before the Norman building was constructed.
