Passage graves comprise a narrow stone-lined corridor, leading into a main chamber, which might have sub-chambers leading off from them. Passage graves are common in Ireland, Orkney, and important sites are located at Bryn Celli Ddu and Barclodiad y Gawres. Such sites are often decorated with rock art, with shared patterns and motifs appearing at passage graves across their distribution.
Tips for visiting passage graves:
- You should not climb on the mound as this will be dangerous for you and could cause damage to the site.
- The ceiling can be low inside passage graves, so please mind your head.
- Beware of uneven floors and low lighting inside passage graves.
Tips for photographing:
- Passage graves are difficult to photograph, due to their size.
- If the mound is covered in grass, the uniform texture of the grass will harm the photogrammetry results.
- Photograph around the outside of the mound; try to get coverage of the outside from different angles.
- Inside the passage and grave, you should walk around taking photographs of the wall opposite you.
- Remember to photograph the floor and ceiling of the passage and grave, too.
- Take photographs from either end of the passage.
- Using a tripod will ensure your photographs are not blurry in the low-lit inside of the passage grave.
- You can use a flash if you need to.
