“Vitoria-Gasteiz 1850: a virtual reconstruction” is an application for general use on mobile devices developed by Arkikus (www.arkikus.com) and commissioned by the Town Council of Vitoria-Gasteiz (www.vitoria-gasteiz.org/turismo).

The virtual reconstruction included in this app aims to show the architectural atmosphere that the town of Vitoria-Gasteiz (Basque Country, Spain) showed in 1850, before the demolition of the gateways that protected the medieval walls and its subsequent modernisation.

All digital content included in this application has been elaborated on the basis of the main image, documentary and archeological resources available at the present time for the reconstructed spaces or, where sources are lacking for certain elements, by using chronologically, geographically and stylistically proximate architectural and/or ornamental parallels, in an attempt to achieve the maximum degree of historical accuracy.The reconstructions that are included display an interpretation of the heritage environment agreed upon by different specialists at the date of creation of the app; new research may well refine this interpretation further.
