Poolbeg

The Poolbeg Lighthouse is located in Dublin, Ireland, at the mouth of the River Liffey, near the Poolbeg peninsula. The lighthouse was first established in 1767 and initially operated using candlepower, which was later changed to oil in 1786. It was redesigned and rebuilt into its current form in 1820.

The lighthouse is a cylindrical tower with a balcony and lantern, standing at a height of 20 meters. It is one of three lighthouses located on the Great South Wall, which extends nearly four miles out into Dublin Bay. The Poolbeg Lighthouse is iconic and commands extensive views of the bay, with an unbroken panorama of the surrounding mountains.

One of the most interesting aspects of the Poolbeg Lighthouse is its history, which dates back to 1767. The original building presented a different appearance, with a sloping roof and an octagonal lantern. The lighthouse has undergone significant changes over the years, but it remains an important aid to navigation in Dublin Bay. Today, the Poolbeg Lighthouse continues to operate, providing a vital service to mariners and sailors in the region.
