Front of Oeiras lime kiln

Five circular lime kilns (Portuguese: Fornos da Cal) made of stone, dating back to the late Middle Ages, were located in Paço de Arcos, Oeiras, Portugal. Four kilns were demolished or incorporated into surrounding buildings[when?] and their gardens, but one was purchased by the municipality in 1989. Archaeological work began in 1994 and the kiln was opened to the public in September 2004. The kilns are classified by the Portuguese Government as a Property of Public Interest.[1][2]
