Helix pomatia, common names the Burgundy snail, Roman snail, edible snail or escargot, is a species of large, edible, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae. It is a European species. It is called by the French name escargot when used in cooking. Although this species is highly prized as a food it is difficult to cultivate and rarely farmed commercially.
Distribution of Helix pomatia includes:
Southeastern and central Europe:
- Germany – Listed as a specially protected species in annex 1 of the Bundesartenschutzverordnung.
- Czech Republic – least concern species (LC): Its conservation status in 2004–2006 is favourable (FV) in the report for the European commission in accordance with the Habitats Directive.
- In southwestern Bulgaria up to an altitude of more than 1600 m.
- Northern and central Balkans
- Bosnia & Herzegovina
- Republic Of Macedonia
- Great Britain: in the west and south of England in southern areas on chalk soils. Its common name in the UK is "Roman snail" because it was introduced to the island by the Romans during the Roman period (AD 43–410). In England only (not the rest of the UK), the Roman snail is a protected species under the Wildlife and Countryside Act 1981, making it illegal to kill, injure, collect or sell these snails.
- Central France
- Netherlands 
- Denmark – Listed as a protected species.
- Southern Sweden
- In central and southern parts of Sweden, Norway and Finland, isolated and relatively small populations occur. It is not native to these countries, but is likely to have been imported by monks from Southern Europe during medieval times.
The shell is creamy white to light brownish, often with indistinct brown colour bands. The shell has five to six whorls. The aperture is large. The apertural margin is white and slightly reflected in adult snails. The umbilicus is narrow and partly covered by the reflected columellar margin.
In southeastern Europe, H. pomatia lives in forests and open habitats, gardens, vineyards, especially along rivers, confined to calcareous substrate. In central Europe, it occurs in open forests and shrubland on calcareous substrate. It prefers high humidity and lower temperatures, and needs loose soil for burrowing to hibernate and lay its eggs. It lives up to 2100 m above sea level in the Alps, but usually below 2000 m. In the south of England, it is restricted to undisturbed grassy or bushy wastelands, usually not in gardens; it has a low reproduction rate and low powers of dispersal.
Average distance of migration reaches 3.5–6.0 m.
Eggs are laid in June and July, in clutches of 40–65 eggs. The size of the egg is 5.5–6.5 mm or 8.6 × 7.2 mm. Juveniles hatch after three to four weeks, and may consume their siblings under unfavourable climate conditions. Maturity is reached after two to five years. The life span is up to 20 years. Ten-year-old individuals are probably not uncommon in natural populations. The maximum lifespan is 35 years.
This species is listed in IUCN Red List, and in European Red List of Non-marine Molluscs as Least Concern.  Helix pomatia is threatened by continuous habitat destructions and drainage, usually less threatened by commercial collections. Many unsuccessful attempts have been made to establish the species in various parts of England, Scotland and Ireland; it only survived in natural habitats in southern England, and is threatened by intensive farming and habitat destruction. It is of lower concern in Switzerland and Austria, but many regions restrict commercial collecting.
