Whilst the exact number of nuraghi on Sardinia is unknown, it is certain that they are in the thousands. One source, for instance, states that there are at least 7,000 of these stone towers on the island, whereas another claims that there are at least 8,000. This large number of monumental stone towers is an indication that the people of the Nuragic culture were master architects and builders. The nuraghi, however, are not the only type of building that was being built by the Nuragic culture.
