Carrickmines Castle – Norman Fort in Dublin’s Pale
Meta Description: Explore Carrickmines Castle, a medieval Norman fortress uncovered during roadworks in Dublin — revealing towers, ditches, and everyday artefacts.
Introduction
Carrickmines Castle was a key defensive stronghold on the southern edge of Dublin’s Pale. Built by the Anglo-Normans in the 13th century, it guarded the frontier between Norman-controlled Dublin and Gaelic Irish lands. Rediscovered during motorway works in the early 2000s, its excavation sparked national debate about preservation and progress.
Historical Role
The castle was constructed around 1240 AD and controlled trade routes and patrol zones for centuries. It featured curtain walls, towers, and inner baileys that stood against repeated Gaelic raids.
Excavation Highlights
As part of M50 construction, emergency digs uncovered:
- Stone foundations and tower bases
- Moats and defensive ditches
- Medieval pottery, coins, horseshoes
- Everyday tools, buckles, and food waste
The Buildings of Ireland register documents its heritage status and post-dig analysis.
Controversy and Compromise
Protests by historians and locals failed to stop development, but they did result in better documentation and preservation efforts. Carrickmines became a national example of how archaeology and modern planning collide.
Legacy
Today, you can visit the site and trace outlines of the original castle, now partially incorporated into modern landscaping around the M50 junction.
