It is named after the typesite of Penard in West Glamorgan, where a hoard of bronze tools from the period was found in 1827.
The period is characterised by a flowering in experimentation in bronze working, spurred by increased contact with the Urnfield culture of Continental Europe from where early sword and shield imports came.
There are links with Reinecke D and early Hallstatt A1 periods, and the French Rosnoën and the Montelius III phases.
Developments included the invention of the cylinder sickle and leaf-shaped pegged spearheads, mirroring an increase in the use of sheet bronze.
