In the next issue of hidden europe, we explore how ancient currents of cross-cultural exchange find expression in the architecture of mosques across Europe, noting how Islamic ideas about geometry and sacred space have informed some of Europe's most striking buildings. And of course plenty about places: from the coast of Liguria in northwest Italy to a cave city in Georgia. We shall also look at what the European Union's new Eastern Partnerships scheme might mean for six ex-Soviet republics in eastern Europe. hidden europe 27 will be published on Monday 6 July.
