The monument comprises the remains of an earthwork enclosure. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric. Tyddyn Tudur enclosure is visible as low earthworks with a central enclosure surrounded by two widely spaced circuits of banks. The area between the two banks has been further divided to make two or more smaller enclosures. Extending from the enclosure are the remains of a once presumably extensive contemporary field system.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
