Howth (; ) is a village and outer
suburb of
Dublin,
Ireland. The district occupies the greater part of the peninsula of
Howth Head, forming the northern boundary of
Dublin Bay. Originally just a small
fishing village, Howth with its surrounding once-rural district is now a busy suburb of Dublin, with a mix of dense residential development and wild hillside. The only neighbouring district on land is
Sutton. Howth is also home to one of the oldest occupied buildings in Ireland,
Howth Castle.
