How to contribute?
– Visit a site registered in the inventory – take photos etc. Please follow the Visiting Best Practice.
-Upload through Inventory 1964-2014 website, by site by parish page
– At the bottom of the site page, there is an upload section (Name, Email address, comment and browse-for photographs).
What to take a photo of?
A photograph of the complete site, features of interest, areas at risk or that have been conserved or restored.
What to comment on?
Ideally we are seeking a current site description, condition and use , other info (memories, associations etc).
Criteria for inclusion
Image Quality
High Quality images are strongly recommended (5 megapixels or above). Set your camera to the highest quality setting.

Blurred/out of focus will not be accepted by the moderators

Tiff (.tif) files rather than JPEG (.jpg) where possible.

For the best quality the use of a tripod in image capture is recommended.

Image Relevance
What does it show? Does it illustrate, compliment or enhance the 1964 record.
The image name should reflect this.
The description in the comments box, should justify the inclusion of the image/images.

The image must have been taken by the uploader. Scanned postcards and other historic scans will not be included.

– Moderation – After publishing your content they will be sent to moderation by the Digital Volunteers before appearing live on the site for others to view.

In addition we are supporting the Heritage Together project.
The focus of the project is on producing heritage data in conjunction with local communities. Photographs of heritage artefacts and environments will be uploaded onto our website (
The project is funded under the Humanities Research Council’s ‘Connected Communities’ call. The project is a collaboration between the schools of Computer Science at Bangor University and Aberystwyth University, and schools of Archaeology at Bangor University and Manchester Metropolitan University and Gwynedd Archaeological Trust. This project builds on a previous AHRC £100,000 project led from Bangor of the ‘Alternative views of the lost heritage of Gwynedd’.
Our goal is to capture all the standing stones and burial cairns, foremostly in the Gwynedd area, but also beyond.
Therefore Photographs of prehistoric sites will be included in this project. In order to ensure the photographs are usable, please read the following guidance:
Photogrammetry works by looking for common features that appear in a set of photographs, then using those features to work out where each photograph was taken from. By doing that it can calculate the structure of the object being photographed and give us a 3D model.
To get the best model, you should follow these tips when you take your photographs.
• Don’t take photographs from the same position, move around the object and taken photographs from different angles.
• Photographs need to overlap, so that the photogrammetry can spot common features. If you walk around a monument and take a photograph every step, you should have enough overlap.
• Remember to photograph and ‘hidden features’, for example the top of the stone (if you can safely reach it) and the underneath of a capstone.
• Don’t digitally process images on your computer before uploading them.
• Try not to take photographs of other people, as we can’t accept photographs with any identifying features for privacy reasons.
What will happen to my photo?
As it is a one year project the site will be archived from 1 January 2015 and data incorporated into National Monument Record (RCAHMW) and Historic Environment Record. Reports will be drawn from the data and made accessible by Cymdeithas Archaeoleg a Hanes Llŷn.
The new data will provide a comprehensive picture of the sites today (their condition and use) and highlight the change that has occurred over the past 50 years. It will identify sites that need further research or conservation work. Importantly through its incorporation into the HER, it will provide an important resource for the management of the Historic Environment.
The CC BY-NC 4.0 creative commons license will therefore allow you to retain your copyright (as photograph author), but will also allow the data to be incorporated into the heritage management systems for future reference.
Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) allows for others to share (copy and redistribute) and adapt (remix, transform and build upon) your work, as long as they credit you for the original creation and it is used for non commercial purposes . This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.

What are the ideal standards required?
The preservation of digital data is still new and being development. However the following best practice, will form the guidelines for the project:

Photographic standards
• Tiff (.tif) files rather than JPEG (.jpg) where possible. JPEG’s are more vulnerable to further degradation during editing and archiving, this is in contrast with Tiff format which is open-source and ideally suited to high-quality capture and long-term archiving.
• Image file title should reflect site name. This is important for archiving as this is known as metadata.

What could I include as a comment?
In order to provide a comprehensive and useful entry why not use the online resources?

RCAHMW Thesaurus of Monument Types for Wales and controlled terminology

Historic Wales is an online portal which combines heritage mapping data from Coflein (Online National Monuments Record by RCAHMW) and Archwilio (Online Historic Environment Record by the Welsh Archaeological Trusts) as well as heritage datasets from Cadw.
For more information see our Heritage Guide, available on request by email:
Why is the text in English?
The reason for this is that it is a product of the time. As the Inventory was written in 1964, English remained the official language of the public sector, and as a result all publications were in English. We have not translated this as it represents the authentic nature of the publication.
T o conform with the Cymdeithas Archaeoleg a Hanes Llyn / Llyn Archaeology and History Society ethos for bilingual engagement with heritage, the site is available in Welsh or English, and we encourage uploads in either Welsh or English.
Why are some sites not included?
Heritage is a changing concept, with today’s sites, tomorrow’s heritage. Therefore back in 1964, sites such as Second World War defences at Porth Neigwl, Penrhos and RAF Nefyn , which we now consider important archaeological sites were not. Furthermore sites new discovered through archaeological surveys and excavation since 1964 are not included. Given the limited scope of this project, we are only focussed on those recorded in the 1964 publication, for the current record of sites, go to Coflein.
Where there has been a new understanding or a change in the condition of the site, we are keen to know.
