Missing Pieces Project: How to Make a Contribution

All over England are places with stories to tell: from buildings to battlefields, some on your doorstep, others just a day trip away. Their stories are still being written, and they won’t be complete until you share your side.

This page provides guidance on how to contribute to the Missing Pieces Project, including what to add, how to add it, and how it will be moderated.

How to make a contribution

Step 1: Sign into your account

If you haven't already, create an account and sign in.

On desktop, you can sign in via the icon in the navigation bar at the top of the page.

On mobile devices, you can find the option to sign in within the burger menu.

Step 2: Search the List

Search the National Heritage List for England ('the List') to find an existing list entry using the text search, map search, or Advanced Search (with extra filters).

Step 3: Choose an entry

Once you've found a list entry you'd like to contribute to, click its link to go to an overview page showing key information such as the listing grade, entry number, and the date the entry was first listed.

Step 4: View existing contributions

Select the Comments and Photos tab. This will show you existing contributions for your selected list entry.

Step 5: Open the contribution window

At this stage, when signed into an account, a yellow box will be visible under the title of ‘Comments and Photos’, prompting you to add your missing pieces. Select ‘add your comments, photos or videos now’ to open the contribution window.

Step 6: Add your missing pieces

A window will appear with the list entry location automatically marked on a map. Enter your text using the ‘Enter your contribution’ box. Add up to four images via the ‘Add your photos’ button, or a YouTube video by clicking ‘Add a YouTube Video’ and pasting your link into the box.

Step 7: Submit for moderation

When you have finished, click the blue ‘Submit for approval’ button to send your contribution to the Moderation team. You will receive a confirmation email once your contribution has been approved.

What can I contribute?

You can add contributions to entries on the National Heritage List for England:

  • Listed buildings
  • Scheduled monuments
  • Protected wreck sites
  • Parks and gardens
  • Battlefields
  • World Heritage Sites

Many list entries are quite brief, particularly older ones. We need your help to tell the stories of these nationally important historic places and expand the information available.

This might include:

  • Text that details the architecture, history or archaeology of a building or site
  • Text that summarises the social history or your personal experience of a historic place. How did it make you feel being there? What questions does this site prompt in you? Do you or your family have a connection to the place?
  • Links to other web pages, such as valuable online resources or connected list entries
  • Photographs that show interiors, exteriors, a site’s place within the wider landscape, or details that demonstrate its character or development
  • YouTube videos that document a site from the air or provide more information about its history

What should I avoid?

🚫 Corrections

If you think a list entry is incorrect, you can let us know by asking for a minor amendment.

Please do not contribute information that can be used to identify an individual.

  • Avoid people and faces in the foreground of photos

🚫 Advertising and promotion

Please do not add contributions that feature adverts or commercial activity. Your contribution may be rejected if it is not historically relevant to the list entry.

Photographs must be yours. If contributing a historical image, you must have the rights to upload it. We may reject or remove photos if we believe this to not be the case or if we receive a complaint of copyright infringement.
