This time i've been flying to Castel del Monte, in the southern region of Puglia, where i could overfly the wonderful Castel of the Emperor of the Roman Empire Fredrick II, built by the 1240, a fascinating ans symbolic world heritage monument, in a octogonal plan, whose design reproduces the golden section in many ways – I was also pleased to see some my old friends Giuseppe Casalino e Luciano Spezzano
