I created Castizo Spain to help other people discover the authentic, smaller, more organic parts of Spanish culture, so you can travel better and travel well.
Spain protects 625 historic towns by law. Most travellers can name six.
That gap is the whole reason this site exists.
The designation is called Conjunto Histórico. It sits in Spanish heritage law alongside the categories for monuments and archaeological sites, but it works differently from all of them. It does not protect a building. It protects a place. The street plan, the rooflines, the squares, the way the houses stack up a hillside. Once a town carries it, you cannot widen a lane or put a new window in a facade without permission.
Some of these are names you already know. Toledo has it. So does Santiago de Compostela, and Cuenca, and Ronda.
And then there is Peñalba de Santiago, up in the Aquilian mountains of León, where a tenth-century Mozarabic church sits in the middle of a slate-roofed village of fifteen people. That has exactly the same legal protection as Toledo.
Why you have not heard of most of them
The obvious objection first. If these places were worth visiting, surely they would already be famous.
Here is what actually happened. Guidebooks have a page count. Travel sites have a traffic problem. Both are solved the same way, by covering the twenty towns people already search for and skipping the other six hundred. It is not a conspiracy, it is arithmetic. A publisher who devotes a spread to a village of forty people is making a bad commercial decision, and they know it.
So the coverage concentrates. Ronda gets written about a thousand times and Rello, a walled village in Soria with twenty-one residents, gets written about approximately never.
The Spanish state took a different view. It has been adding to this list since the 1940s and it is still adding. Molinaseca was declared in 2021. Sahagún in 2022. Bembibre in 2023. Hoyos, in Cáceres, in 2024. Nobody stops to write a listicle when a village of nine hundred people gets national protection, but the protection is the same.
This is the part worth understanding, because it changes how you read the list.
A Conjunto Histórico is not an opinion. It is not a magazine's pick or a tourism board's campaign. Someone from the regional government surveyed the place, wrote up why the fabric of it matters, and published a decree with a reference number. The file exists. You can look it up.
That makes it a much better filter than "prettiest villages in Spain," which is a filter for photogenic and nothing else.
It also means the list contains things you would not expect. About 47% of these declarations are not named after a town at all. Spain has applied the same designation to a fishermen's cove on the Costa Brava, to a canal running through three provinces, to a Barcelona street, to the royal shipyards. S'Alguer, in Girona, is a cluster of stone boat huts with a recorded population of one.
The useful ones, for a traveller, are the places you can actually walk around. That is what this directory covers.
What I found while building it
I expected this to be a data exercise. Take the official register, pull the towns out, build a page for each.
The register turned out to be less complete than it looks.
Spain's heritage lists are published province by province, and they are maintained by volunteers. That works well for the famous entries and badly for the rest. When I checked the Canary Islands against the official provincial list, the list held fourteen towns. Reading every Canarian municipality's own record turned up ten more, including Puerto de la Cruz, which is a resort town of thirty-one thousand people declared by decree in 2006. It was simply missing.
So I stopped trusting the lists and read everything instead. Every populated place in Spain with a written record and a population figure. All 23,798 of them.
That found another thirty-one towns nobody had catalogued, and the pattern in them is consistent. Piornedo, in the Sierra de Ancares, a pre-Roman village of thatched stone pallozas. Tazones in Asturias, where Charles V came ashore in 1517 and where the rocks still hold dinosaur tracks. Navarrete in La Rioja, which was invisible because La Rioja has no published provincial list at all.
Two regions still have no official list. Madrid and La Rioja. Everything the directory holds for those two came from reading individual town records one at a time, which is worth knowing when you judge how complete any of this is.
"So it is a list of empty villages"
Not quite, and the spread is worth knowing before you plan anything.
At one end, yes, there are the near-abandoned ones. Cardet has eight residents. Baños de Panticosa, a Pyrenean spa at 1,630 metres, has ten. Caracena in Soria has thirteen. These are day trips or detours, not places to base yourself, and the pages say so.
What is actually on the site
Every one of the 625 towns gets the same treatment. That is the point.
A photograph. Where it is, on a map. Population, elevation, and the year it was protected, with the reference number where the register carries one. A written overview of its history and what survives. The other protected towns near enough to reach in a day. Where to eat, when there is anywhere to eat.
There are no rankings. No top ten, no "best of," no scores. Ranking Peñalba de Santiago against Toledo would be a category error, and any number I attached to it would be invented.
There is also nothing sponsored, and no town has paid to appear. The list is the legal register. A town is on it because Spain protected it, which is the only qualification that means anything here.
The parts that are thin, and why they stay thin
Some of these pages are short.
Twenty-five of the towns have fewer than sixty residents. Three have no restaurant at all. Thirteen have almost nothing written about them anywhere, so their pages carry a photograph, the facts, and not much else.
I could have padded those. It would have been easy to widen the restaurant search until something turned up two valleys away, or to generate a few paragraphs of atmosphere about a village nobody has described.
That would make the directory worse. If a page says there is nowhere to eat in Aldea de Ebro, that is because there is nowhere to eat in Aldea de Ebro, and you should pack a sandwich. A directory that is honest about fifteen-person villages is more useful than one that pretends every entry is a weekend break.
The same rule runs through the data. Two Atlantic ports here, Muros and Baiona, carry an elevation figure in every source I could find, and in both cases the figure is the height of a mountain inside the municipality rather than the town. Both sit at sea level. So those pages show no elevation at all, because a blank space is better than a confident wrong number.
How to use it
Start with a region if you know roughly where you are going. All seventeen are covered, the Canaries and the Balearics included, and each one opens onto its provinces and then its towns.
Start with a city if you are already booked somewhere. There are twenty-seven of them, from Seville to Santander to Las Palmas, and each lists the protected towns within a day's drive. Not a straight line on a map. An actual drive, which is why Formentera's villages do not show up under Ibiza despite being twenty-two kilometres away.
Or start with a single town, because you saw a photograph and want to know whether it is worth the detour. That is the question most of these pages exist to answer.
Spain has been quietly protecting these places for eighty years. The list has never been collected in English in one piece before. It is here now.
