This postcard came from Piotr (6 July 2016) Postcrossing.  Being a seaport, a postcard of Świnoujście will naturally feature a ship (a ferry is shown).  This postcard shows also (top right hand corner) the lighthouse (built in 1858) of  Świnoujście.  This lighthouse which is 68 m high is the tallest lighthouse in the Baltic Sea.
