The Great South Wall - A feat of incredible engineering when it was completed in 1795, the Great South Wall was built by the British Empire to protect Dublin’s busy port. It stretches 4 km out to sea, making it one of the longest sea walls in Europe. At the end is an 18th century lighthouse, painted bright red and from there the views back to Dublin city are fantastic. There’s usually a mobile coffee shop parked at the start of the walk if you need a pick me up. #views #walking #dublin #sea
