As you leave the boat, you will notice the Customs Square on the right side of the port. A postwar creation, the Customs Square replaced the old coal sheds, and now in their place stands the "Monument of the Unknown Sailor", a memorial which honours the Greek Sailors. It is a highly significant piece of the famous sculptor, Yiannis Pappas, and its construction was funded by the Goulandris family - a well-known Greek shipping family. It was placed in Teloneiou Square in 1974.
There is a rich history which draws visitors to see the Customs' House in Syros. It was designed during the the time of the island's economic boom, and it was built by architect Alexandros Georgantas between 1859 and 1861 in order to house Syros' Customs office. It is a two-storey building with isodomic marble walls and many fine marble details.
A section of the Customs' House was destroyed during the Second World War, but it was rebuilt immediately after.
These days, you'll notice a platform which is designed to tie up and dock the ships, as they are required to go through customs control. The locals refer to the surrounding area as "Nissaki".
