then the Balsaggart Stream. The island of Ireland's Eye, part of the Special Area of Conservation, lies about a kilometre north of Howth harbour, with Lambay Island some 5 km further to the north. A Martello tower exists on each of these islands with another tower overlooking Howth harbour (opened as a visitor centre and Ye Olde Hurdy Gurdy Museum of Vintage Radio on 8 June 2001) and another tower at Red Rock, Sutton. These are part of a series of towers built around the coast of Ireland during the 19th century. Special amenity area order (SAAO) More than half of Howth Head, and of the Howth area, totalling around 1,500 acres, is subject to a Special Amenity Area Order, a provision of Irish law designed to protect areas of natural beauty or biodiversity. Prepared by the local authority, after a consultative process under a community environmental process known as SEMPA, and formally proposed by Brendan Howlin as a minister, the order was developed in cooperation with a unit of Trinity College Dublin. It was made in 1999, confirmed in 2000, and is subject to 5-yearly reviews, the most recent having been conducted in 2015.

The SAAO area runs from the vicinity of Bottle Quay northeast to Muck Rock, east to the reservoir at Balkill, east and south around the Loughoreen Hills and Black Linn, then to the Summit, turning north along the line of the Coulcour Brook, then taking in a narrow part of Howth village, including the Martello Tower and East Pier, and Ireland's Eye.

Fingal County Council explained the need for the order, noting that between the 1940s and the present day "Howth has been transformed from a rural area to
