A year ago I made a very constructive post about the influence of the Goths in Spain, and while the goths did leave a strong trace there (you can find visigothic names in Portugal, Spain and Latin america even today), they were mostly assimilated in the latim culture of those areas
So, there is any place on europe or the middle east were the visigoths or the ostrogoths can settle and keep their culture as the main local culture?
