Under the sweltering Turkish sun, tourists wander through sets that recreate Ottoman and Byzantine-era castles, take selfies with actors in traditional Ottoman costumes and watch horseback stunt performances. Among them is Riia Toivanen, 22, a devoted fan of Turkish television drama who traveled to Istanbul from Finland with her mother to delve into the realm of her beloved shows.

Some 8,000 miles (12,800 kilometers) across the globe in Villa Carlos Paz in Argentina, 66-year-old retired teacher Raquel Greco watches an episode of a Turkish romantic comedy, surrounded by memorabilia from her once-in-a-lifetime trip to Istanbul where she visited landmarks she knew from years of watching Turkish shows.
