The Poolberg lighthouse, built in 1768, is located in Dublin Bay. It was probably the first in the world to illuminate travelers with candles, but as early as 1786 the light source was turned into crude oil. Today, it is a distinctive centerpiece of Dublin's port and quay.
Interestingly, the Poolbeg lantern painted with red paint is made of limestone and is up to 20 meters high. However, today's appearance of the lighthouse is the result of its reconstruction in 1820 - previously it was smaller and more soaring. It is located on the Great South Wall, one of the longest sea walls in Europe, and at the time of its creation it was one of the longest in the world.
The Poolbeg lighthouse offers a beautiful view not only of the ocean, but also of Howth's heather-covered hills and the rugged coastline of Ireland with cliffs and rocks.
