Wicklow: History, Harbour and Coast

Wicklow brings together historic sites, coastal views and activities on the water. The Wicklow Town Heritage Trail winds through narrow streets and historic sites; Black Castle stands on a rocky promontory above the sea. At the harbour, you can enjoy a range of activities all year round. These different highlights give your stay in Wicklow its own character – from town history to the coast.

Town History on the Heritage Trail

The Wicklow Town Heritage Trail winds through the town’s narrow streets and past historic sites, while also letting visitors experience the coast. Across 25 stops, the trail covers Wicklow’s history, from the arrival of Saint Patrick in 432 to the founding of the Irish Free State in 1922. Along one route, you can encounter both early religious history and a later political turning point.

A free guided tour takes place every Saturday at 11:00. It begins on Easter Saturday and ends on the last Saturday in September; the meeting point is outside the Wicklow Tourist Information Centre on Fitzwilliam Square. As the tour runs seasonally, please check the dates before your trip. The Captain Halpin’s Trail offers another historical perspective, leading to places significant in the life of Captain Robert Halpin.

The Abbey Grounds are also part of Wicklow’s history. They contain ancient monastic ruins of historical significance to the town. The Abbey Grounds are also associated with the Taste of Wicklow festival as a venue.

Black Castle and Wicklow Gaol

Black Castle stands on the eastern side of Wicklow Town, on a rocky promontory above the sea. At the mouth of the Vartry River, a fortified, strategically positioned rocky outcrop later became the site of a castle: the structure now known as Black Castle. From the ruins, you can look out over the town and the North Wicklow coast. Access is from South Quay or Castle Street; check local conditions before your visit.

Restored Wicklow Gaol was begun in 1702 and not completed until the 1840s. People were imprisoned there for breaching the Penal Laws, as were many rebels after the 1798 Rebellion. The prison’s history includes early prisoners, rebels such as Billy Byrne, and deportations to the penal colonies of Botany Bay and Van Diemen’s Land. For planning your visit, please note that, as of 16 September 2026, Wicklow’s Historic Gaol is closed for renovation work. Check its status before visiting.

Cliffs, Lighthouses and Harbour

Wicklow Head is 3 km from the town centre. Three modern lighthouses stand there, having guided ships on the Irish Sea. From Wicklow Head, views extend over Wicklow Town, the harbour and the coast. The Wicklow Head Cliff Walk also features archaeological sites; prehistoric flints were found in a rock shelter.

When walking the cliff path, be mindful of trail conditions: there are some climbs, and on sections near unprotected cliffs you must walk single file. Rare birds nest along the route, and you can spot seals on the beaches. Dogs must be kept on a lead and must not approach the seals. Glen Beach lies at the start of the cliff walk and offers peaceful coastal views, as well as views of the grey seals that live there.

At Wicklow Harbour, visitors and locals can swim, row, fish, bathe and walk all year round. The harbour is home to the Wicklow Sailing Club, the RNLI Lifeboat Station and Conway Port. Wicklow therefore offers a mix of interests: a historic walk through town, coastal paths with nature and history themes, and activities on the water.
