When we travel to an old city, there is usually a list waiting for us. A temple, a palace, a fort, a particular street, perhaps a museum before lunch. We look at the important things, take the photograph, read the paragraph beside it and move on.
But some of the most revealing places are the ones where you can spend an afternoon simply walking around. The old house with its oddly placed windows. The narrow street that seems too narrow until you learn what the weather is like. A well built into the middle of a neighbourhood. Workshops that still make things by hand. Ruins scattered across a landscape rather than gathered neatly behind one entrance.
Keeladi, outside Madurai, Tamil Nadu, is one of those places where the small finds are especially interesting. Archaeologists working at the settlement have uncovered brick structures, terracotta ring wells, roofing tiles, spindle whorls, beads, iron objects, gamesmen and pottery, among other things. Carbon dating has placed some of the material around the sixth century BCE, while Tamil-Brahmi inscriptions have added to evidence of writing in the region. The settlement grew along the Vaigai, and the excavated material gives a picture of an organised community involved in craft production, trade and everyday domestic life.
A spindle whorl is hardly the sort of object people travel across a country to see. But it tells you that someone was spinning thread. A bead tells you somebody was making jewellery. A game piece suggests that someone, at some point, had time to sit down and play. Archaeology gets interesting when these things begin to add up.
In Yazd, Iran, much of the old city developed around a more immediate problem: how to live in a very hot, dry landscape without wasting water. The qanat system carried groundwater through underground channels, sometimes over considerable distances. Traditional houses were built around courtyards and often included spaces below ground, while windcatchers directed air into the interiors. Thick earthen walls helped keep the heat out. The result is a city in which the climate is present in almost every architectural decision.
The same attention to surroundings appears in Lamu, off the coast of Kenya. The old town developed over centuries as part of the Swahili trading world, with ships bringing goods and people across the Indian Ocean. Coral stone and mangrove poles became building materials; houses turned inward towards courtyards; streets remained narrow and largely pedestrian. Walk through the old town and the geography of trade is still visible in the buildings. Materials came from the coast, objects arrived from overseas and architectural ideas travelled with the people who came and went.
Aksum, in northern Ethiopia, gives you another glimpse of how far ancient trade networks could reach. The city was the centre of the Aksumite kingdom, which flourished from around the first to the eighth centuries CE, with connections extending across the Red Sea. The remains include enormous stone stelae, tombs, inscriptions and the ruins of earlier settlements. Greek, Sabaean and Ge'ez inscriptions found here are particularly useful evidence of a society communicating across different linguistic and cultural worlds.
The mountains around Yemen produced cities that look as though they have been fitted into the rock rather than built beside it. Thula is one example. The historic settlement sits against a sandstone cliff, enclosed by defensive walls, with tall stone houses rising several floors above narrow lanes. Some of the oldest evidence at the site comes from inscriptions associated with the Himyarite period. The location also gave the settlement access to mountain agriculture and water while making it easier to defend.
Nearby, Shibam Kawkaban occupies a similarly dramatic setting. The historic settlement is divided between the town at the foot of Mount Kawkaban and the older city above it. There are rock-cut tombs dating back to the Sabaean and Himyarite periods, along with old buildings, cisterns and agricultural terraces. The route between the settlements follows the steep mountain terrain, and the landscape makes clear how much effort went into making a high-altitude settlement work.
Sana'a, also in Yemen, has an entirely different kind of density. The old city has been inhabited for more than 2,500 years, and its traditional houses can rise several storeys, with decorated façades, coloured plaster and distinctive windows. From the outside, they can look almost theatrical. Inside, however, these were family homes, with kitchens, storage areas, rooms for receiving guests and spaces arranged around the needs of daily life. The height allowed families to live within a compact city while leaving precious ground space for other uses.
Ancient Merv, in Turkmenistan, takes the idea of an old city in another direction. There is no single historic centre to wander through because Merv was repeatedly rebuilt. The settlements developed around the Murgab river oasis, and different cities occupied the area at different times. At its height, Merv was one of the major urban centres of Central Asia. Today, its remains are spread across a vast archaeological landscape of walls, settlements, mausoleums and traces of streets and buildings.
Standing there, the absence of modern life becomes part of what you notice. The city depended on water from the oasis and on its position along major routes. Those advantages could make a settlement wealthy and important for centuries, but they could not guarantee that it would remain so forever. Merv is a useful place to think about how much of a city's survival depends on things that are beyond the control of the people living in it.
That is what makes these places worth seeing beyond the standard monuments. The details tend to stay with you. A water channel running beneath a desert city. A house designed around a courtyard. A narrow lane made for pedestrians. A bead found in the soil. A mountain settlement reached by a steep path. A trading town whose buildings still carry traces of goods and ideas that arrived from another shore.
You begin to notice that an old city is made up of thousands of practical decisions. Where to build, what to make, what to trade, how to keep cool, where to find water, how to protect a home, how to move through the streets. Those decisions are still sitting there, sometimes thousands of years later, waiting to be noticed.
