The opinion that persists around the toponymic name of the area,
Tunes, is that it was so named for the number of colonists from north Africa, primarily from
Tunis. Those who believe in this origin site the medieval French marigold (
Tagetes patula) flower of Tunes, a herbaceous plant similar to the
carnation (with cut petals and yellow flower) and common in Tunes, Portugal as well as in
Tunisia. The civil parish was created on 4 October 1985, under Decree-law 130/85, making it the youngest of the parishes of Silves. The settlement developed primarily around the
junction of various rail-lines that connected Lisbon to the Algarve. In the 19th century, the locality was dominated by a few agricultural settlers who dedicated themselves to wine production. The first barrios began to appear after the railway opened in Gateiras. What was planned initially was a station would be constructed in Algoz, near the village of Tunes. But, owing to the slope of the hills, the construction of the station was differed to several kilometres to the east. The population was composed primarily of workers for the railway. On 21 February 1889, the first train passed through Tunes on the Lisbon-Faro line. It was on the same line, specifically the Tunes-Lagos link, that the last steam-powered train was used in the Algarve (in 1972). It was also in 1972 that the first thermoelectric plant was inaugurated in the community. The economic changes in the country over time transformed the civil parish from one of agricultural and industry to a more tourist-oriented speciality. ==Geography==
