The
name Benllech is perhaps a mutated form of
penllech, literally "head slab" or "head rock", i.e. "capstone" or "head of the rock", or possibly meaning 'on slate', shortened from the Welsh term 'ar ben llech'. Benllech is a seaside resort and beach holiday destination. The Village also has a range of businesses which include public houses and hotels, camping and caravan sites and several
bed and breakfasts. The community has a primary school, Ysgol Goronwy Owen; library, doctors' surgery, chemist, several churches, hardware store, two community centres, police and fire station, tennis court and bowling green, a number of supermarkets (Spar, Cooperative and Tesco Express), restaurants and a petrol service station. Between 1909 and 1950 there was a
railway station close to the village which was the terminus of the
Red Wharf Bay branch line. The old station house and several railway bridges can be seen along the road approaching the village. Situated on the outskirts of Benllech lies the Scheduled Monument Pant-Y-Saer enclosed hut group, otherwise known as "Cytiau'r Gwyddelod" (Irish Huts). The monument consists of a complex of mainly circular huts and parts of an associated substantial enclosure wall lying on a slightly elevated limestone plateau area beside an old lane running from Llanbedrgoch to Llanfair Mathafarn Eithaf, about 0.6 km S of the modern settlement of Benllech. The monument is of national importance for its potential to enhance our knowledge of prehistoric/ Romano British settlements. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive. ==Notable residents==
