Torre de Pisa, "torre pendente di Pisa",🇮🇹 mini🧵👇

¿Te parece toda "blanco mármol"?

La roca más utilizada en la construcción de la torre
es el Mármol de San Giuliano , en los cimientos, la estructura cilíndrica y las columnas.

Y la caliza gris oscuro de Filletole, utilizada sobre
todo en las bandas oscuras ornamentales de la fachada.

La mayoría de las rocas procedían de canteras
próximas, situadas en los montes Písanos y en el área
de Oltre Serchio

En restauraciones se utilizó el Mármol de Carrara para sustituir al de San Giuliano.

También hay calcarenitas, granodioritas, granitos y serpentinitas
