Thanks to children who kicked up little pieces of red ceramics while playing on a hilltop in 1977, the town of Mértola, Portugal, has taken its place alongside much of the rest of the country as it rediscovers its Islamic past. Years of excavations have turned Mértola, which lies near the border with Spain, into a destination for both tourists and researchers, and officials have applied to make Mértola a UNESCO World Heritage Site.
