Albulae Aquae ("White Waters") is a group of springs located 6 kilometres (3.7 mi) west of Tivoli, Italy. Its Latin name derives from the ancient Roman settlement here. The spring water is bluish, strongly impregnated with sulphur and carbonate of lime, and rises at a temperature of about 24 °C (75 °F). The principal spring, the "Lago della Regina", is continually diminishing in size owing to deposits left by the water. Dedicatory inscriptions in honour of the waters have been found at the site. The deposits form travertine stone which is still mined for building material. The remains of Roman thermal baths are nearby, which used the thermal springs. They are locally known as the baths of Queen Zenobia as she lived in a villa nearby after she was brought back from Palmyra in 274. It is mentioned briefly by many ancient authors, among them, Virgil, Vitruvius, Isidore of Seville, and Pliny the Elder:Iuxta Romam Albulae aquae volneribus medentur, egelidae hae, sed Cutiliae in Sabinis gelidissimae suctu quodam corpora invadunt, ut prope morsus videri possit, aptissimae stomacho, nervis, universo corpori. The tepid waters of Albula, near Rome, have a healing effect upon wounds.Those of Cutilia, again, in the Sabine territory, are intensely cold, and by a kind of suction penetrate the body to such a degree as to have the effect of a mordent almost. They are remarkably beneficial for affections of the stomach, sinews, and all parts of the body, in fact.

Hadrian's Villa (Italian: Villa Adriana; Latin: Villa Hadriana) is a UNESCO World Heritage Site comprising the ruins and archaeological remains of a large villa complex built around AD 120 by Roman Emperor Hadrian near Tivoli outside Rome. It is the most imposing and complex Roman villa known. The complex contains over 30 monumental and scenic buildings arranged on a series of artificial esplanades at different heights and surrounded by gardens decorated with water basins and nymphaea (fountains). The whole covers an area of at least a square kilometre, an area larger than the city of Pompeii. In addition to the villa's impressive layout, many of the buildings are considered masterpieces of architecture, making use of striking curved shapes enabled by extensive use of concrete. They were ingenious for the complex symmetry of their ground plans and are considered unrivalled until the arrival of Baroque architecture in the 1600s initiated by Borromini who used Hadrian's Villa for inspiration.The site, much of which is still unexcavated, is owned by the Republic of Italy and has been managed since 2014 by the Polo Museale del Lazio.

Pozzo del Merro is a flooded sinkhole in the countryside northeast of Rome, Italy. Situated at the bottom of an 80 m conical pit, at 392 m (1,286 ft) it is the second deepest underwater vertical cave in the world. In 2000 two ROVs were sent to explore its depths; the first, the "Mercurio (Mercury)" reached its maximum operative depth of 210 m (690 ft) without reaching the bottom. The second ROV, "Hyball 300", reached 310 m (1,020 ft) without touching down either. A third dive in 2002 with the more advanced "Prometeo" robot reached the bottom at 392 m (1,286 ft), but discovered a narrow passage continuing horizontally.The sinkhole, similar to the Zacatón cenote, was formed by volcanic activity eroding the carbonate rock.
