Yemen 50 Rial - which building is depicted on obverse and what is size?

Found this Worldofcoins from  eurocoin http://www.worldofcoins.eu/forum/index.php/topic,60601.0/topicseen.html

On the other side it depicts Aidrus Mosque, which is located in Crater district, Aden Governorate. Below the mosque is the word 'Aden'. The Houthis do not currently control any part of Aden Governorate, which also includes the city of Aden. Aden is the temporary capital of Yemen that is being used by the government of Yemen, as the Houthis control the original capital Sanaa.

 Ah, beat me to it -

The coin depicted by Eurocoin is not correct.

The numerals in the year differ from Press release and photograph.
