Such buildings are in every nook and cranny of the worlds.....even we'll developed countries.
And the good thing is that objects can be fixed, renovated and as an Eritrean I don't even recommend that we destroy them and build new on their spots.
We still can do that around the vacant territories of our cities and towns.
And what makes Asmara a comfortable city is the fact that it is built with out of this world blue prints so much so, it is not necessary to build eye sore high rises glasses and bricks buildings neither does it need a city light train system. One can zig zag from point to point B at ease unlike the rest of the congested other African countries.
Side note.
Every body knows that colonization is brutal and we the Eritreans know how to differentiate its cruelty with what the colonizers left behind intact unlike sellassie and mengistu who destroyed our properties.
But when you see them filthy agames try to make joke about our old buildings, it really sound like they were jealous that Italy didn't colonize them, even though they were colonized by Eritrea willingly for the fact they were flooding Eritrea in the 300 thousands of them to be Eritreans slaves so much so if one can dissect every young agame's skinny body one will definitely find Eritreans households donated pieces of injeras through the DNA of their parents and grandparents.
