its beauty and occupies the area to the west of the town, connecting St Columb and St Mawgan churchtown. Town St Columb occupies a plateau at about elevation. The north part of the town (known as 'Bridge') descends into the Vale of Lanherne, having a minimum elevation of approximately . It was originally a linear settlement built on the main road running north-east to south-west, but modern estates have since been built, extending the town to the south and east. In the older part of the settlement there is much high-density housing with relatively narrow streets, and a number of retail outlets and public houses; the more modern estates have housing which is generally lower in density. To the south there is an industrial estate. Settlements Besides the town, there are numerous villages and hamlets in the parish, including Talskiddy and Gluvian in the north, Ruthvoes (southeast), Trebudannon (south), Tregaswith (southwest), Tregatillian (east) and a large number of smaller farming settlements and isolated dwellings. There are also Halloon, Lanhizey, Rosedinnick, Tregamere, Trekenning, Tresaddern, Trevarron, Trevolgas and Trugo. Rivers A number of small rivers and streams flow through St Columb parish, most rising in the eastern part and flowing west. One of the sources of the River Fal lies just within the boundary on the Goss Moor; this flows southwest to the South Coast. The River Menalhyl, which flows through the north part of St Columb (Bridge), has three branches with a confluence at Gilbert’s Water, just to the east of the town. The longest of these rises next to the Nine Maidens standing stones in the north part of the parish. The Menalhyl was historically important in the area, powering a number of mills along its course. A smaller river rises near Winnard's Perch (north of Talskiddy), later joining the Menalhyl near its mouth at Mawgan Porth. The other main river of the parish is the unnamed one (often called the River Porth) that rises to the east of Ruthvoes, and that in its latter course fills the Porth Reservoir and enters the sea at St Columb Porth. This is the river that, according to legend, was begun by the blood of the murdered Saint Columba running down the valley.
