 Emblem

The crest of Drogheda United is an adaptation of the crest of Drogheda town´s coat of arms, which feature the heraldic symbols of a star and crescent over a shield depicting St. Lawrence´s Gate, three lions and a ship. The three lions passant represent England - as Drogheda lay within the Pale and was a garrison town - and the ship represents the town´s port.

While Drogheda United share the same symbols and colours as Trabzonspor, in Turkey - both recently declared to be brother teams - this has nothing to do with the Sultan of Turkey´s attempted relief of the Irish during the Great Famine of the nineteenth century, as the town coat of arms pre-dates the Great Famine by almost eight hundred years

Taken from wikipedia, I couldnt find a picture to show of crest of Drogheda town though, sorry, but thought this might clear up the reasons behind it

Premiership club Portsmouth FC also have the star and crescent:-

Funny, I always think of it as the ranch in "The Thorn Birds".....Thanks for letting me know!

The rumor is that there is a related stone inscription on a wall of the historical Drogheda Municipality Building (now WESTCOURT HOTEL).

Official letter of thanks from Ireland to the Ottoman Sultan is still displayed in a Turkish Museum.

In a recent ceremony held by the inscription, Turkish Ambassador Taner Baytok said, this story appeared in an essay by Thomas P. O´Neill in THE TRESHOLD magazine (1957).

AlphaF sen çok akýllýsýn, how do you know so many things???!!!!! below is the essay you are talking about

TURKISH HELP TO IRISH DURING FAMINE

How wonderful that two countries so far apart are connected in such a wonderful and generous way, I learnt about this (story in the above hyperlink) when i was learning about the Irish famine in history class in school (a good few years ago haha)and I have always thought about this history whenever I have visited Turkey

Quoting Cem Özmeral October 2, 2008 Dublin, Ohio, from the above excert

"And I must add ; hopefully this story can reflect the reader in ways that can reveal a great deal for everyone willing to really understand that; ethnic, religious and cultural differences between us are all our strengths when it comes to caring about each other."

Here is a puzzle for those who may want to know more about the Ottoman star and crescent symbol that appears on Drogheda FC amblem.

The coin above is not Ottoman. In fact, Ottoman Empire did not exist when that coin was in circulation. Any idea who printed it ? and why Ottomans may have adopted the symbol on the coin?

Yes, i know that coin. It´s Byzantine coin. But the same sign can be seen on Memluk Turks´ flag and Gokturk coins. I haven´t seen the coin in real though
