Just outside the southern gates of the Museum-Reserve is Bolgar's most spectacular modern sight - the White Mosque. The mosque was officially opened in 2012 and, as its name suggests, is completely white. The mosque's central dome has a diameter of 10 metres and its two side minarets are 46.5 metres tall. Surrounding the mosque is a beautiful arcade of 88 columns and in front of it there is a central fountain. It is just as beautiful inside with elegantly carved arches and a beautiful red and gold coloured carpet.
