Serdika is The first place that I have visited in Sofia, it is the center or the heart of the capital Sofia.. The most interesting thing there is that there is a great sign of peace and love which means "we have to respect other people believes and civilisations.. You can see when you walk in Serdika the beautiful green church, and in another side..very close the big ottoman Mosque and in another side also the Temple of the Jews.. three religions met in the same place and in the same country with all fraternity and love.. "Love and peace" is my favourite title which I chose to give to Sofia and then to Bulgaria as a whole ❤️.
