Here was formerly a convent of Carmelites, another of Capuchines, another of barefooted Carmelites, three nunneries, an hospital, and a convent of Guillemins, in which is the tomb of Theodore Martin, who brought the art of printing out of Germany into the Low Countries. Alost was taken and dismantled by Marshal Turenne in 1675; and after the battle of Ramillies in 1706, was abandoned to the allies. The population by the last census amounted to 10,926, a great proportion of whom trade in corn and hops, or are engaged in brewing. E. Long. 3. 56. N. Lat. 49. 55.
