The river wraps around it on three sides.
Toledo's old town occupies the top of a hill around which the Tagus bends on three of its four sides. That curve in the river — and the rock cut it has carved — explains the size of the city, the gradient of its streets and why you can only enter across two bridges.

01 A bend in a river
The city is on the river's right bank, set into its meander. This is not a position chosen for the scenery: it is a textbook defensive position, with water acting as a moat on three of the four sides and only one of them open to the plateau.
And there is a clue in the name itself. Toledo comes from the Latin Tollitum, which passed through Tollitu, Tollito, Tolleto and Tolledo. The meaning attributed to it is "raised" or "elevated", though there is an alternative reading linking it to the double bends or meanders the river forms. Both readings describe exactly what you see from the viewpoint.

02 The hill in figures
The city stands at 529 metres and the municipality covers 232.1 square kilometres, but that last figure misleads: the protected historic centre is 259.85 hectares, with a buffer zone of 7,669.28. That is, two and a half square kilometres of old city and seventy-six of protected surroundings.
UNESCO inscribed the Historic City of Toledo in 1986, at its tenth session, under four cultural criteria: i, ii, iii and iv. Four of the six available. That is not a routine inscription.
03 There are only two ways in
The practical consequence of the meander is that, historically, crossing the river into the old town was done by two bridges and only two: Alcántara, Roman in origin, upstream, and San Martín, medieval, downstream. Both still stand and both are still the natural way in on foot.

Both bridges are fortified, with gate towers. That is not decoration: if your city has two entrances, those two entrances are the city. The river's bend did the work of thirty kilometres of wall, and on the open side the wall did have to be built.

04 What the bend prevented
A city shut inside a meander cannot grow outwards: it grows inwards and upwards. That is why Toledo's old town is what it is — extremely narrow streets, steep gradients, irregular blocks, dead ends — and why the modern city is entirely outside it, to the north, on the flat.
And that is why the old town survived. There was no room inside the perimeter for nineteenth-century extensions or property operations: the rock and the river did not allow it. What was demolished in other Spanish cities to open avenues stayed standing here because the avenue would not fit.
05 How to look at it
Start from outside. The city cannot be understood from within, because from within all you see is streets three metres wide. Cross to the other side of the valley and look at it head-on: in a single glance you get the hill, the rock cut, the river's curve and the two bridges closing it at either end.
Then walk the perimeter. There is a route along the bank, at the foot of the escarpment, that follows the meander; it is the only way to gauge the real height of the hill above the water and to see how much rock lies beneath the houses.
And once you are up there, stop looking for the plan. There is none: the old town's fabric answers to no grid, it answers to the slope. If you get lost — and you will — go up. Every street that climbs ends in the upper town, and from the upper town you can get anywhere.
