Halfway along the old road from Samarkand to Bukhara, where the Zeravshan valley widens into irrigated plain, there is a ruined town called Dabusiya. The Sogdians founded it, and it grew into a staging post on the Silk Road, where caravans paused for water, fodder and trade. The Arabs reached it in the early eighth century and the town held out and changed hands as the region went through conquest and conversion. By the Middle Ages it was a modest brick town with a citadel, a mosque and workshops. The Mongols and later shifts in the river sealed its decline.
The remains today are fragments of fortification, low earthen swells and the outlines of streets, set among cotton, wheat and melon fields. It is the kind of site where the history is mostly imagined from the shape of the ground, and nothing prepares you for the quiet. There is a small area of signboards but little in the way of facilities, so the visit is short and thoughtful, with the rest of the time given to the road.
The road is what this stop is really about. The highway between Samarkand and Bukhara runs across a flat, dry steppe plain of about two hundred and fifty kilometres, and it is straightforward but demanding in its own way. Surfaces vary between smooth modern asphalt and broken sections with potholes, trucks move in convoys, and heat in summer reaches the forties, with strong sun and long distances between shade. Spring brings green fields and poppies, autumn is warm and golden, and winter can bring fog.
Yangirabot, about seventeen kilometres away, is a town of some size, and it is the sensible place for fuel, bread and a meal. Beyond it, small roadside cafés and chaikhanas, tea houses, serve lamb kebab, plov and green tea at wooden platforms called tapchans, where you can take off your boots and lie down in the shade. Fuel can be hard to come by in Uzbekistan, with shortages of petrol at times, so fill up whenever you can and carry a reserve. Bring plenty of water, wear sunscreen, and leave early to get the best of the day.
