Holy Trinity Column The square on which it sits, Horní náměstí (Upper Square), was briefly named Adolf Hitler Platz
Riga Brivibas iela was was renamed "Adolf Hitler strasse" during the Nazi occupation (and then "Lenin iela"!!") It IS included within the inscribed area which consists of Old City, Boulevards and Suburbs. Brivibas Iela goes out from the edge of the old city and is shown in both these areas (marked 2 + 3) on the UNESCO map. Also quote from AB review "National Romanticism evolved from Jugendstil in Latvia, again on the Finnish model. This movement is represented by the work of architects such as E. Laube, K. PekSens, and A. Vanags, with some striking examples of their work in Alberta and Brivibas Streets."
