Entry 01 · Towers
Seventy towers, fourteen survivors, and a commune that legislated the sky
Fourteen towers survive of the seventy-odd that once stood; they are a family arms race in stone, and the commune eventually legislated a maximum height to stop it.

Entry 11 · Papers
The wall in Prato held a merchant’s whole working life
Francesco di Marco Datini of Prato left roughly 150,000 letters and 500 ledgers, walled up in his house and rediscovered — the most complete surviving picture of how a medieval merchant actually worked.

Entry 02 · Towers
The commune built the tallest tower itself, and then made it the limit
The tallest survivor, built by the commune itself, which is the point — the public tower had to out-top the private ones.

Why a register
A tower is evidence, and so is a bill of lading
This site takes the position that the two are the same kind of object: something that survived, in a place with a name, from a century we can bound. The register is the argument; the entries are the notes to it.
Where the record disagrees with itself the entry says so rather than choosing. Castel del Monte is the clearest case. Where a date, an attribution or a document cannot be shown, the entry is left open — six of the sixteen carry no comune at all, because a technique has no address.
Entry 07 · disputed
Castel del Monte, and four ways of reading it
Frederick II’s octagon near Andria has an octagonal courtyard and an octagonal tower at each corner, almost no defensive apparatus and no documented programme. The entry carries all four readings and endorses none.

- iA hunting lodge, on the pattern of the emperor’s other Apulian residences.
- iiA crown in stone: a symbolic seat, built to be seen rather than lived in.
- iiiA geometrical exercise, its proportions carrying astronomical or numerical intent.
- ivA castle after all, of a kind whose military logic we no longer recognise.
The register, mapped
Entry numbers are pin numbers
Every located entry carries its comune, so the register can be read as a map without being rewritten. Nine places are marked; the technique entries have no address and are not on it.
Five sections
Sixteen entries. No date, attribution or document invented; where the record is silent, the entry says so.
Under the masthead
Keepers of the same stones.
The register is kept by its supporters. Nothing on these pages is written for them, and none of them chooses what is entered.
