The territory of the commune of Brouqueyran is vulnerable to various natural hazards: weather-related events (storms, thunderstorms, snow, extreme cold, heat waves, or droughts), floods, and earthquakes (very low seismicity). A website published by the BRGM (French Geological Survey) allows for a simple and quick assessment of the risks to a property located either by its address or by its plot number.
The commune has been recognized as being in a state of natural disaster due to the damage caused by floods and mudslides that occurred in 1982, 1999, 2009, and 2020.
The shrinkage and swelling of clay soils can cause significant damage to buildings in the event of alternating periods of drought and rain. The commune is at medium or high risk (67.4% at the departmental level and 48.5% at the national level). Of the 86 buildings surveyed in the commune in 2019, all 100% are at medium or high risk, compared to 84% at the departmental level and 54% at the national level. A map of the national territory's exposure to clay soil shrinkage and swelling is available on the BRGM website.
Furthermore, to better understand the risk of ground subsidence, the national inventory of underground cavities allows for the identification of those located within the commune.
Regarding landslides, the commune was recognized as being in a state of natural disaster due to damage caused by drought in 2011, 2015 and 2017 and by landslides in 1999.
For Dauzat, Brouqueyran comes from a Gallo-Roman name of man, *Broccarius, from the Welsh broccos, "taish", with the suffix -anum. Jacques Astor, quoted by Bénédicte Boyrie-Fénié, also thinks that the name comes from *Broccarius, with another meaning (the Welsh broccos also has the meaning or connotation of "prominent").
Bénédicte Boyrie-Fénié, part of testimonies that are once by Brouqueyran, once by Beucoiran, in Moulis-en-Médoc: Becoiran (Petrus de ~), in 1242-1255 (Beucoiran), Brouqueyran (ecclesiam de ~), in 1261 (Broqueiran), Bolcayran, dates (Beucoiran), Belcorano, undated (Beucoiran), Bolqueran / Bolqueyran, undated (Beucoiran). The sense of broc (cf. Welsh broccos, "taish" and Latin brochus, "the one with the prominent teeth or the prominent mouth, that exceed) and the one of beak, word only medoquin, is first "thorn" and the derivatives of the first designate bartàs, places full of white broc or white broc. By adding the collective suffix (set of...) Latin -ariu(m) and the locative suffix (the place where there is...) -anu(m), Brouqueyran, like Beucoiran and also like Espiet (< Espinet-), were, according to B. Boyrie-Fénié, places full of bushes, when they arrived.
In 1763, Abbot Expilly described the village as follows:
During the French Revolution, the parish of Saint-Pierre de Brouqueyran became the commune of Brouqueyran.
The Château de Mirail is privately owned and not open to the public. Its southwest tower houses a chapel with remarkable facades, roofs, and decoration, as well as a fireplace adorned with a sculpted relief depicting the Denial of Saint Peter. The entire complex was listed as a monument historique by decree in 1990.
