Portrane or Portraine (Irish: Port Reachrann) is a small seaside village located three kilometers from the town of Donabate in Fingal, County Dublin in Ireland.

[1] Portrane has an approximately 2 km (1.2 mi) long sandy beach backed by sand dunes in places on the north end.

At the very north end of the beach is a National Heritage Area which is visited by various migratory birds during winter time.

Built in the early 1900s, the asylum is made up of a number of Victorian red brick buildings which dominate the peninsula.

[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.

[10] Lead singer Bono was baptized at Portrane beach by the Shalom religious group which all but Adam Clayton were a member of.
