Hello,  one more from  the Gold Coast as this is a lovely stamp and showing a castle with some interesting history.

It is actually Osu Castle  also  know as Christiansborg Castle and is found in Accra, Ghana.  You can read more if you are interested but in summary it is on the coast of the Gulf of Guinea and is a substantial fort built by Denmark-Norway in the 1660s.  It changed hands a few times with Portuguese then British ownership before Ghana took control after independence. 

Enjoy the history behind the stamps   Michel  cddstamps.com
