factorium

From faciō (“to do, make”) +‎ -tōrium, or equivalently factor (“doer, maker”) +‎ -ium; the person who pressed olives in an oil-press was called a factor, and the oil produced was called factum. Compare calcātōrium (“winepress”).

factōrium n (genitive factōriī or factōrī); second declension

1. An oil-press
   • c. 500 CE, Palladius, Opus agriculturae 11.10.1:

     Nunc oleum viride faciemus hoc genere. Olivam quam recentissimam, cum varia est, colligis et, si diebus aliquot collegeris, expandis, ne calefiat. Si qua ibi putris aut sicca est, removes. Ubi vero conpleveris modum factorii, sales tritos vel non tritos, quod est melius, in olivam eandem mittes per decem modios tres salis et moles primo et sic salitam in novis canistris esse patieris, ut pernoctet cum salibus et ducat in se eosdem sapores: ac mane premi incipiat olei meliorem fluxum redditura salis sapore concerto.

2. (Can we verify⁽⁺⁾ this sense?) A place for the purpose of making, creating or fabricating.

Second-declension noun (neuter).
