Early Cretaceous limestone became known as “Vratza stone” and it enjoys great popularity still today.

    The reason is that it has an elegant understated character with a colour ranging from white to light yellow, it is dense and hard wearing and it is frost resistant.

    A British importer states that it is the only white limestone they would recommend for use in a kitchen.

    Vratsa limestone's credentials and reference buildings are numerous, in Bulgaria and abroad. References in Sofia include the Alexander Nevsky Cathedral (exterior), National Palace of Culture, the Cyril and Methodious National Library, and Sofia University's Rectors Building. Outside Bulgaria, the most prominent references include the Swaminararayan Mandir - a Hindu Temple in northwest London, England, the National Museum in Vienna, Austria, the University of Gothenburg in Sweden and the Royal Bank of Scotland.
