Within the territory of the Danube Delta, there are four lighthouses, all concentrated in Sulina (and its immediate vicinity), which has earned the town the nickname "The City of Four Lighthouses." Their placement here is due to the fact that the Sulina branch is the only one of the three Danube branches that allows navigation for maritime vessels.
Currently only the new lighthouse at the arm’s mouth is operational, and it can be seen at night from 19 nautical miles away. With a height of 49 meters, the lighthouse was built between 1977 and 1983, on ferroconcrete pillars drilled 30 meters deep.
The other two lighthouses downstream from the town of Sulina were taken out of operation in 1925, but the one on the left bank remains a tourist attraction which also appears in the screenplay of the novel "Toate pânzele sus".
But certainly, the most visited of all is the Old Lighthouse of the European Commission of the Danube located near the city center. Built between the years 1838 – 1841 in the area of the Danube’s mouth of those times, the lighthouse is working as a museum since 2003. However, in the past, in addition to the role of navigation, it was also used as a shelter for shipwrecked sailors or for those who wanted to escape pirate attacks, the inner yard having the shape of a small fort.
The museum exhibits various objects, documents and photographs from the period of the European Commission of the Danube, but there are also two rooms, one dedicated to George Georgescu, composer and conductor born in Sulina and the other to Eugeniu Botez, alias Jean Bart, maritime commissioner and writer, author of the novel "Europolis".
