Which sources count

The operator first: the museum for its own tickets, the transport authority for its own fares, the city for its own buildings, the organiser for its own dates. A tourist board or a newspaper is used only where the operator says nothing, and it is named on the page when it is.

When official sources contradict each other, we follow the one responsible for the thing being described. When even that does not resolve it — when a single official site says two different things — the claim does not appear at all.

Deleted, not hedged

Anything that cannot be verified, that conflicts between sources, or that is likely to change is removed. It is not printed with “reportedly”, “around”, “unconfirmed” or a note telling you to check it yourself. If removing it leaves a sentence that no longer reads, the sentence is rewritten; if it leaves a section with nothing behind it, the section goes.

Where a page does point you at an official site, it is next to a fact we have already verified — never instead of verifying it.

Every page carries the date it was checked

At the foot of each guide is the date its facts were last verified by hand. The date is not a publication date and not an automatic timestamp: it moves only when someone has gone back to the sources.

The pages those checks were made against are archived, so a correction can be traced to the wording that was live at the time.

How often each kind of fact is re-checked

Prices and admission rules: every three months. Schedules that the operator republishes month by month, such as the changing of the guard: monthly. Seasonal information with a short shelf life, such as which Christmas markets have published their dates: every two weeks while the season approaches, then weekly.

Where a page depends on something with an end date — building work, a temporary walkway, a government-funded fare reduction — that end date is written into the page and into the check schedule.

When something is wrong

A mistake found on one page is corrected on every page that repeats it, not only where it was spotted. Several errors have travelled across this site that way: a museum described as the world’s only surviving ship of its kind, an animal that is not in a zoo’s own list, a city described as entirely cashless.

Each correction is then pinned down by an automated check that fails the build if the old wording reappears. That is why the same error does not come back after an editing pass.

Commercial relationships

There are none. This site does not sell tickets, passes or tours, and takes no commission when it names one. Passes are compared against the venues’ own prices, and the comparison is allowed to conclude that the pass does not pay off.

Telling us something is out of date

Prices move, buildings close for restoration, ferries change piers. If a page here disagrees with what you found in front of you, that is worth knowing — with the date you were there, it can be checked against the operator’s own page and fixed the same way everything else is.
