Twelfth-century Silk Road traders relied on a network of caravanserais (roadside compounds). Doorways wide enough for camels and open courtyards offered sleeping bays for traveler and animal. A great place to resupply and trade trinkets. Illustration by Always with Honor

It’s dark and you’re far from home. Where do you stay? Back in the day, you had to know somebody. Nowadays your smartphone does.
