As in Windhoek, there are lots of historic German buildings dating to the turn of the 20th century, most of them in perfect condition. The railway station, the prison, the Woermann House, the Kaserne (barracks), the Lutheran church, and the district court look more like illustrations from some Brothers Grimm fairy tale than the working buildings they once were. You can usually purchase a book with detailed information about these buildings from the Sam Cohen Library, which is worth a visit for its impressive collection of Africana books, archives of old newspapers (many in German), and vast photo collection (though note the N$50 users' fee to browse the archives). This library began its life with 5 books and now has over 10,000 volumes.
