This application connects Liepaja's past and present. It has been exhibited in 2022 by the Digital Innovation Park in cooperation with the association "Liepāja 400" as part of a project co-financed by the Liepāja Culture Board. The purpose of the application "Old Libau" is to show, with the help of augmented reality, how the specific places depicted in the photographs of the time, when Latvia was still moving towards its statehood and independence, look like today.
