Achaea (Greek: , Achaïa; see also List of traditional Greek place names) is an ancient province and a present prefecture of Greece, on the northern coast of the Peloponnese, stretching from the mountain ranges of Erymanthus and Cyllene on the south to a narrow strip of fertile land on the north, bordering the Gulf of Corinth, into which the mountain Panachaicus (1,902 m, the northernmost mountain range in the Peloponnese) projects. Achaea is bounded on the west by the territory of Elis, on the east by that of Sicyon, which, however, was sometimes included in it. The population in 2001 had reached over 300,000.
In Ancient Roman times the name of the province of Achaea was given to the whole of Greece, except Thessaly, Epirus, and Acarnania. It is in this latter enlarged meaning that the name is always used in the New Testament (e.g., Acts 18:12, 27; 19:21; Romans 15: 26; 16:5).
In the 13th century the Principality of Achaea was founded in Greece after the Fourth Crusade.
The Principality of Achaea fell to the Ottoman Empire. The area was later invaded by the Venetians in the late-16th and the 17th centuries and later invaded by the Ottomans again. In 1821, it became part of Greece. Achaea or Achaia later produced several heroes including Kanaris and Roufos and prime ministers of Greece including Andreas Michalakopoulos as well as some head of states.
In the 20th century, the Area which excluded Metochi reverted from Ilia as the municipality of Kalotychia became Vouprasias. That part had been a part of Ilia, then Elis during the ancient times. Another reorganization reverted Mataranga and Spata into the prefecture of Achaia and the municipality of Larissos.
A mid-1994 late-night (around 3 AM local time) earthquake rumbled the area with a magnitude around 5 on the Richter scale. This was a minor one. It was after another earthquake. A forest fire consumed the northern part of the Panachaicus in the mid-1990s.
Mudslides numbering around 1,500 occurred between 1950 and 2005 according the university study, much of the mudslides occurred to the north and the central parts. Mudslides are one of the most in all of Greece.
Aigion is a seaside city with a city hall and a city square is in its heart. The population is around 30,000.
Kalavrita is a town situated more than 70 km (45 miles) to the east via the road from Achaea's capital. A few kilometres to its west is a monastery situated on the peak of the hill. Its name is Aghía Lávra. 12 to 20 km east, is Cave Lakes where lakes are inside this brilliant cave. It is open to tourists, and the length is around 300 to 500 m. A skiing resort is on Mount Chelmos. The mountain hosts the most modern greek telescope, named Aristarchus (after the ancient Greek astronomer - Aristarchus of Samos) and operated by the National Observatory of Athens A narrow gauge railway track runs for 30 km and acts as a tourist attraction (mainly). The track begins near Kalavrita and ends off Diakopton. Patras
Temeni is a place where the famous spring water Avra (Άυρα) or Aúra is manufactured. It is owned by Tria Epsilon, a division of Coca-Cola Company and a parent.
There are no oil refineries except for a small refinery near Rio.
The main highways are 8 (longest), 8A (E55), GR-9 (E55, E65), GR-31, and GR-33.
A beltway which bypasses Patras begun construction in 1990, and extended construction to GR-33 in 1992, Savalia in 1993, East Patra or Patras in 1995, and in 1998 into GR-8. Lights were installed in the early 2000s on the beltway, and opened to traffic on late 2003. It starts from near Roitika and ends just south of Rhion.
GR-8 was the first superhighway, along with GR-5 in the prefecture. The beltway is the second, and the bridge will be the third. Its length now has almost 100 km (60 mi) of superhighway. Its length was only 70 to 75 km until 2003.
The Rio-Antirio bridge, which started construction in 2000 (though plans had been made throughout the 1990s, and was supposed to begin in those years), opened in mid-2004, connecting the mainland and the Peloponnese. This eliminated much of the ferry service which has been used for about half a century for automobiles. Since then, there is only the rare ferry service in the city of Aigio(n), which is the ferry route to Aghios Nikolaos in Phocis.
