Most people who have travelled through Usakos - since virtually nobody travels 'to' it - will have one vivid recollection of the town: the distinctive water tower with the witch's hat.
In a climate as arid as Namibia's, where evaporation can easily exceed the rainfall by a factor of ten, conserving what little water is available is a major priority. Where possible, water storage facilities need to be sealed to prevent evaporative loss - there is no apparent reason why that roof needs to be pointed and witchy, but it's a splendidly Germanic touch!
This water tower is part of the old railway station complex and was built to supply the steam locomotives that ran on the Usakos-Karabib-Tsumeb-Grootfontein line until 1960, when the service converted to diesel.
The Ned Geref Kerk ('People's Reformed Church') in Usakos is an endearing architectural mongrel that isn't quite sure whether it wants to be a church or a castle!
The fact that there is an NGK in town is significant, as this is an Afrikaans Protestant church and indicates that at least some of the farming community around Usakos has South African - as opposed to German colonial - origins.
Many of Namibia's small towns - which is the vast majority, as there aren't many 'big' ones - have a distinctive timewarp feel about them.
This is particularly true of Usakos. Part of the reason why the main street feels so forgotten is that it has been bypassed by the main road: at the sign shown in the photo, you bear right for Swakopmund. This means that the main road carries no through traffic and is only frequented by the local population (quoted as being 9147 according to the GeoNames geographical database at the time of writing in November 2011).
