The Flavian Amphitheater is the third largest Roman amphitheater in Italy. Only the Roman Colosseum and the Capuan Amphitheaters are larger. It was likely built by the same architects who previously constructed the Roman Colosseum.
It was begun under the reign of the emperor Vespasian and probably finished under the reign of his son Titus. The arena can hold up to 50,000 spectators. The interior is mostly intact and one can still see parts of gears which were used to lift cages up to the arena floor.
In 305, the arena was the setting for the persecutions of the patron of Pozzuoli, Saint Proculus, and the patron saint of Naples, Saint Januarius. After surviving being thrown to the wild beasts in the arena, the two were beheadedat the nearby Solfatara.
The elliptical structure measures 147 x 117 meters, with the arena floor measuring 72.22 x 42.33 meters.
The Flavian Amphitheater is the second of two Roman amphitheaters built in Pozzuoli. The smaller and older amphitheater (Anfiteatro minore) has been almost totally destroyed by the construction of the Rome to Naples railway line. Only a dozen arches of this earlier work still exist.
The site of the structure was chosen at the nearby crossing of roads from Naples, Capua and Cumae. It was abandoned when it was partially buried by eruptions from the Solfatara volcano. During the Middle Ages, the marble used on the exterior was stripped, but the interior was left alone and is perfectly preserved. Excavations of the site were performed 1839 to 1845, 1880 to 1882, and finally in 1947.
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
