Piscina Mirabilis

Bacoli, Italy

The Piscina Mirabilis was a freshwater cistern on the Bacoli cliff at the western end of the Gulf of Naples. One of the largest freshwater cisterns built by the ancient Romans, it was situated there in order to provide the Roman western imperial fleet at Portus Julius with drinking water.

The cistern was dug entirely out of the tuff cliff face and was 15 metres high, 72 metres long, and 25 metres wide. It was supported by vaulted ceilings and a total of 48 pillars. It was supplied with water from the main Roman aqueduct, the Aqua Augusta, which brought water from sources in Serino near Avellino, 100 kilometres distant, to Naples.

The ancient cistern is currently in private hands, but parts of it may still be visited by the public.

Despite saying it was open (on Google Maps) we arrived there to find it closed and only open by pre-booking (see attached photo).

A water deposit from Romans period. To find it is a little adventure and to finally enter too. You need to phone to a cell number indicated at the entrance. The person doesn't speak English and we need to phone her sec fetal Tim new because the was a bad signal coverage?. Explanations in Italian many times interrupted by new incoming visitors.

Stavanger Cathedral

Stavanger Cathedral is Norway's oldest cathedral. Bishop Reinald, who may have come from Winchester, is said to have started construction of the Cathedral around 1100. It was finished around 1150, and the city of Stavanger counts 1125 as its year of foundation. The Cathedral was consecrated to Swithin as its patron saint. Saint Swithun was an early Bishop of Winchester and subsequently patron saint of Winchester Cathedral. Stavanger was ravaged by fire in 1272, and the Cathedral suffered heavy damage. It was rebuilt under bishop Arne, and the Romanesque Cathedral was enlarged in the Gothic style.

In 1682, king Christian V decided to move Stavanger's episcopal seat to Kristiansand. However, on Stavanger's 800th anniversary in 1925, king Haakon VII instated Jacob Christian Petersen as Stavanger's first bishop in nearly 250 years.During a renovation in the 1860s, the Cathedral's exterior and interior was considerably altered. The stone walls were plastered, and the Cathedral lost much of its medieval looks. A major restoration led by Gerhard Fischer in 1939-1964 partly reversed those changes. The latest major restoration of the Cathedral was conducted in 1999. Andrew Lawrenceson Smith is famous for his works here.
