Karakorum
"This was the centre of the world. The grass has grown back over it, which is its own kind of statement."
There is a dissonance in Karakorum that no amount of reading prepares you for. In the thirteenth century, this was the capital of the Mongol Empire — the administrative hub of the largest contiguous land empire in human history, home to diplomats from France, Persia, Korea, and China, a city of skilled craftsmen, foreign merchants, twelve Buddhist temples, two mosques, and a Nestorian Christian church operating simultaneously within its walls. William of Rubruck, a Flemish monk who arrived in 1254 on behalf of the French king, wrote a detailed account of it. Today you stand in a small town on the Orkhon River, listening to the wind move through the grass where those walls stood, and the gap between the account and the reality is so large it becomes interesting in itself.

What remains is Erdene Zuu — the monastery built in the sixteenth century using stones quarried from Karakorum’s ruins, its white walls studded with 108 stupas and enclosing temples whose interiors hold lacquered Buddha statues, ceremonial silks, and painted thangkas accumulated across four centuries. The monastery survived — barely — the Soviet-era purges of the 1930s that destroyed most of Mongolia’s religious infrastructure, and the monks who returned after 1990 found buildings intact enough to restore. I arrived early on a weekday morning when the main gate was just opening, and two elderly monks in saffron and maroon were walking between the temples, their breath visible in the cool air, their conversation inaudible but continuous. I followed at a respectful distance without understanding anything and found it completely sufficient.
The Orkhon Archaeological Landscape around the town is a UNESCO World Heritage site, and the museum in Karakorum itself holds the artifacts recovered from the site — stone inscriptions, ceramic fragments, the carved stone turtle guardians that once marked the corners of the ancient city. There are four turtles in total; two remain in place in the fields surrounding Erdene Zuu, sitting in the grass as if they have always been there, which they have. One is close to the monastery wall, mostly intact. I sat beside it for a while. A group of Mongolian schoolchildren arrived, photographed it on their phones, and left. The turtle remained indifferent to all of this.

The town of Kharkhorin — as it is officially named today — offers a handful of guesthouses and local restaurants where the khorkhog is cooked in the traditional method: lamb and vegetables sealed in a metal pot with hot stones, which cook the meat from inside as the stones release their heat. The result is a dish with a smokiness that comes from the rocks themselves, and a richness that makes the steppe outside feel like the right context for eating it. I shared a table with a German archaeologist who had been excavating the site for three seasons and who spoke about the foundations of the great palace with the specific excitement of someone who has been wrong about something important and is grateful for the correction.
When to go: May through September, with June and September offering the best balance of weather and quiet. July brings tour groups following the Naadam circuit but the landscape absorbs them. The site is accessible year-round, though winter access requires preparation and patience with the roads.
