How to read a heritage record without confusing its dates

The first date you notice in a heritage record may not be the date the building was built. Before using it in a caption, timeline or castle description, check what the field actually records.

The National Heritage List for England provides a useful example. Its entries bring together identification, designation and architectural history. Reading those elements separately helps you write a clearer account of a place.

Start with the exact entry

Save the entry number and check the location and heritage category before taking notes. Historic England gives each entry a unique seven-digit reference. The category tells you whether you are reading about a listed building, scheduled monument or another kind of designated place.

Keep that reference beside your notes rather than relying on the building name alone. When you return to check a detail, you want to reopen the same record.

Separate the record dates from the building dates

The field “Date first listed” records when the entry was added to the List. “Date of most recent amendment” records an update to the entry. Neither field supplies a construction date. Historic England explains these distinctions in its guide to understanding list entries.

Bodiam Castle makes the difference clear. Its listed-building record, number 1044134, gives 3 August 1961 as the first listing date. The architectural description places construction in the years after 1385, when Sir Edward Dalingridge received a licence to crenellate. Those dates describe different events. Read the Bodiam Castle entry.

A useful note would therefore keep two separate lines: construction after 1385; first listed in 1961. Writing “built in 1961” would confuse the record's history with the castle's.

Attach each date to an event

As you read, pair every date with a verb: built, extended, restored, dismantled or listed. Then ask which part of the site the sentence describes.

For example, a date attached to a restoration should stay attached to that work when you summarise it. Do not let it become the date of the whole building. Preserve qualifications such as “probably” or “after” too. A concise description can still show uncertainty.

Read a short description carefully

Historic England explains that older entries can be brief and that descriptions are not comprehensive accounts of a building's interest. The History and Details sections are starting points, with selected sources providing further reading. See its guidance on descriptions and sources.

If your question concerns a feature the entry barely discusses, record the question rather than filling the gap. Look for a source that addresses that feature directly.

Before publishing a summary, make one final pass: does every date have a clear meaning, does every claim point to the right entry, and have you preserved the source's uncertainty? That small check makes a castle's history easier to understand without making it sound more certain than the record allows.
