The Village is surrounded by mountains on three sides and the sea on the other. Would-be escapees who make it to sea are tracked by CCTV and perimeter alerts, which trigger the arrival of Rover, a seemingly intelligent capture pod resembling a huge translucent white balloon. Rover repatriates escapees who make it to sea and occasionally kills (by absorbing and asphyxiating) whomever it is instructed to by Number Two and/or other high-ranking Village officials. Everyone uses numbers for identification, although names are infrequently used. Most of the villagers wear a standard outfit consisting of coloured blazers with piping, multicoloured capes, striped sweaters, plimsolls, and a variety of headwear, with straw boaters being prominent. Several facilities are listed on a local map of the Village, including the labour exchange, hospital, palace of fun (which is never seen), old people's home, and the green dome where Number Two resides. A taxi service operates around the village's buildings. The village of Portmeirion in north Wales was used extensively for exterior scenes of the Village. Rover has the capacity to subdivide, which is seen on one occasion. A robotic device was initially created as the prop for the series but it was replaced by meteorological balloons by the time filming began.
