List of Hewitts and Nuttalls in Wales

Class Prominence
600 m prominences ≥ 600 m
2,000 foot Marilyns 150–599 m
Hewitts 30–149 m
Nuttalls 15–29 m

This is a list of mountains in Wales over 610m.

Nuttalls are hills in England and Wales that are at least 2,000 feet (610 m) high with a relative height of at least 15 m (49 ft). The list was compiled by John and Anne Nuttall and published in The Mountains of England & Wales.[1]

Hewitts are hills in England, Wales and Ireland that are at least 2,000 ft high with a relative height of at least 30 m (98 ft). This list was compiled by Alan Dawson and originally published in The Relative Hills of Britain[2] under the name Sweats. The list was subsequently renamed Hewitts, updated, and published in The Hewitts and Marilyns of Wales.[3]

Other than the inclusion of Ireland, the only difference between Nuttalls and Hewitts is that hills with a relative height between 15 and 30 m are Nuttalls but not Hewitts. This corresponds to roughly a quarter of all Nuttalls, and the exclusion of these least prominent Nuttalls was one of the reasons why the list of Hewitts was produced.

In the tables below, rows have been coloured according to which list(s) the hills are on. Hills that are additionally Marilyns or that are on the list of hills with a 600 m drop are also distinguished. In the parent column, the prominence parent is used where possible. The prominence parent of a peak can be found by dividing the island or region in question into territories by tracing the runoff from the key col of every higher peak. The prominence parent is the higher peak in whose territory the original peak resides.[4] Prominence parentage data is unavailable for Nuttalls and Hewitts, so the hills' parent Marilyns are shown. The parent Marilyn of a hill is the Marilyn whose territory a peak resides in.

There are 190 Nuttalls on the list, of which 138 are Hewitts, and 53 are Marilyns.

Wikibooks has a book on the topic of: Welsh/Pronunciation


  1. 1 2 3 4 5 6 7 Waun Garnedd-y-filiast, Waun Lefrith, Waun Camddwr, Cnicht north top, Craiglwyn, Foel Meirch and Moelwyn Mawr north ridge top were all added to the list of Nuttalls between the first and second editions of the book.[5]
  2. 1 2 Carnedd y Filiast north top and Castell y Gwynt were added to the list of Nuttalls in September 2007,[6] and at the same time Cadair Bronwen northeast top was removed.[7]
  3. Mynydd Graig Goch was resurveyed and found to be 609.75 m,[8] and therefore a Hewitt and a Nuttall.
  4. Traditionally, the top of Maen Du (674 m at SH823152) was regarded as Maesglase's summit. However, more recent surveys suggest that the top of Craig Rhiw-erch (c. 676 m at SH817150, some 600 m to the west) is higher.[9]
  5. The Black Mountain straddles the Wales–England border, and is therefore sometimes included on English lists too.
