Carrickfergus Castle

Short Introduction

Carrickfergus Castle is a Norman castle in Carrickfergus, County Antrim, Northern Ireland.

It stands on the shore of Belfast Lough and is one of the best-preserved medieval castles in Ireland. The castle has played an important military role for centuries and is a strong choice if you enjoy castles, coastal views, military history or historic day trips from Belfast.

Northern Ireland’s Department for Communities describes Carrickfergus Castle as a Norman castle on the northern shore of Belfast Lough, begun by John de Courcy after his 1177 invasion of Ulster, and notes that it remained militarily important until 1928.

What You Can See and Do

Carrickfergus Castle is a proper stone castle with towers, walls, courtyards and a strong defensive setting by the water.

You can explore the castle buildings, learn about its Norman origins, and understand how it was used through different periods of Irish and British history. The castle was besieged by Scots, Irish, English and French forces, which gives it a long and varied military story.

It is especially useful if you want a historic attraction within easy reach of Belfast. You can combine castle history with a walk along the waterfront, a visit to Carrickfergus town centre, or a wider trip around Belfast Lough.

Making the Most of Your Visit

Carrickfergus Castle works well as a half-day heritage stop.

Take time to look at the castle from outside as well as inside. Its position beside Belfast Lough is part of what made it so important, and it also makes the castle more photogenic.

If you are staying in Belfast, Carrickfergus can be reached as a day trip by car or public transport, depending on your plans. It can also be part of a wider route along the Causeway Coastal Route.

Because it is a historic building, expect steps, stone surfaces and areas that may not be suitable for everyone with mobility difficulties.
