There are imposing remains of the Roman therms of the ancient antique city of Alauna (today Valognes), built in the 1st century AD. The edifice was built in a symetric plan and had about ten rooms, including a steam room, a hot pool and a cold pool. The masonries were elevated at about a dozen metres and neatly built, associating small cubic stone block bases to brick layers.References:
The Walhalla is a hall of fame that honors laudable and distinguished people in German history. The hall is a neo-classical building above the Danube River. The Walhalla is named for the Valhalla of Norse mythology. It was conceived in 1807 by Crown Prince Ludwig in order to support the then-gathering momentum for the unification of the many German states. Following his accession to the throne of Bavaria, construction took place between 1830 and 1842 under the supervision of the architect Leo von Klenze.
The memorial displays some 65 plaques and 130 busts covering 2,000 years of history, beginning with Arminius, victor at the Battle of the Teutoburg Forest in 9 AD.
