[3] Lescar is the site of the Roman city known variously as Benearnum, Beneharnum or Civitas Benarnensium, the location providing the name for the later region of Béarn.

[4] In 841, Benearnum was razed by the Vikings and Morlaàs became the Béarnaise capital.

[5] The remains of the last monarchs of all Navarre Queen Catherine I (†1517) and King John III (†1516) lie at the cathedral.

Today, Lescar is primarily a suburb of the nearby town of Pau.

The commune of Lescar has joined together with 30 neighbouring communes to establish the Communauté d'agglomération Pau Béarn Pyrénées which provides a framework within which local tasks are carried out together.
