“Mogadiscio – Moschea Scek Ibraim”
Where is it located? Possibly somewhere near or in between the old El Gab market and Xamar Weyne. Please post your suggestions below using the Comment feature.
The same mosque appears in this older postcard below. Taken from the same angle, you can see the same well in front of the mosque..

Im 100% sure that the mosque Scek Ibrahim is located in “Colombia street” 2* 01′ 13.57″ N, 45* 20′ 25.32″ E. At that time was beside the “Casa d’Italia” or ” circumlocution del tennis”
I meant to say circolo del tennis
Thanks very much. Maurizio. The decimal location address is 2.037093, 45.340338
