Portrane

Portrane's most prominent feature is Tower Bay, and Portrane asylum, more commonly known as St. Ita's Hospital. Built in the early 1900s, the asylum is made up of a number of Victorian red brick buildings which dominate the peninsula. Features within the main asylum building include two churches and an imposing clock tower. The building operated as a mental hospital for many years with it finally closing to inpatients in 2011 and outpatients in 2014 before being refurbished and repurposed as a modern mental health facility. Following the sale of the Central Mental Hospital in Dundrum in 2012 it was announced that it would relocate to the updated St.Ita's facility in Portrane.[3][4][5]

In the hospital grounds is a monument to George Hampden Evans, a replica of an Irish Round Tower.

Portrane Castle (sometimes called Stella's Tower) is a 3-storey late medieval castellated tower house adjacent to St. Catherine's housing estate. Jonathan Swift's 'Stella', Esther Johnson is said to have stayed there and given the castle its unusual nickname. The inquisition of 1541 mentions the castle as being a substantial structure with associated outbuildings including a threshing house and hemp yard while the Civil Survey of 1655 describes this site as an old castle with a thatched hall adjoining owned by the parsonage of Portrane. A later brick chimney can also be seen at the top of the tower.[6][7] Samuel Lewis describes the castle as long since deserted in his Topographical Dictionary of Ireland in 1837 and notes the last occupant was Lady Acheson.[8]

Today the castle sits in a field of privately owned tillage land.

The Church in Portrane was granted to the Convent of Grace Dieu in the 12th century. Originally called St. Canice's, a new church was built in the 14th century and renamed St. Catherine's. St. Catherine's was coupled with St. Patrick's, Donabate, with the Vicar of Donabate serving in Portrane, with the decline of St. Catherine's the parish was linked to Donabate in the 17th century, and only eventually merged in 1835. Many of the Evans family from Portrane Castle are buried in the graveyard.

Members of the band U2 owned a caravan in a field in Portrane where they composed some of the music and lyrics for their 1981 album, October.[10] Lead singer Bono was baptized at Portrane beach by the Shalom religious group which all but Adam Clayton were a member of.[11][12] Rock band the Delorentos are Portrane natives.[13]
