Cherbourg-en-Cotentin is commemorated by this 0.73€ stamp issued by La Poste on 10 July 2017. The light is on the end of the Jetée du Homet in the right-center of the stamp. While not actually a lighthouse, it is still a lighted aid to navigation. Cherbourg is located on the north coast of France and has a fine deep water harbor.

On 29 April 2017 Lietuvos Paštas released a set of two stamps featuring ancient castles. One of the stamps shows the 13th century Klaipėda Castle, also called Memel Castle. In the lower center of the stamp we see what is know as a torch beacon or swape. It consists of a basket of burning coals suspended from a pole and marks the channel entrance to a harbor near the castle. The stamp is based on a 17th century drawing of the area. I would say that we have come a long way in aid to navigation technology!
