What is "altena"

Altena is a town in the district of Märkischer Kreis, North Rhine-Westphalia, Germany. The town's castle is the origin for the later Dukes of Berg. Altena is situated on the Lenne river valley, in the northern stretches of the Sauerland.

The Altena was a Dutch motorcycle and automobile made by NV Haarlemsche Automobiel & Motorrijwielfabriek, based in Haarlem-Heemstede from 1900 to 1906.

The first car built was powered by a 3.5 hp De Dion single-cylinder powerplant. From 1905 models having 8, 10, and 12 hp engines were offered.
