The Eiffel Tower Lighthouse is a unique feature located at the top of the iconic Eiffel Tower in Paris, France. This lighthouse functioned as a beacon for ships navigating the nearby Seine River and was part of the tower's original design by engineer Gustave Eiffel. The light was first illuminated in 1900 and could be seen from several kilometers away. The lighthouse is equipped with a rotating light that flashes every five seconds, making it a notable landmark in the Parisian skyline. Although the original light was replaced in 1985, the current system continues to serve as a symbol of the tower's historical significance and architectural brilliance.
