Piraeus is the gateway to Athens , which, in turn, is rightfully considered the center of the centers of the whole world, with the main attraction - the acropolis. Piraeus is an old port city serving the port of Athens, the largest port in Greece to date. Piraeus is part of the great Athens, which boasts an abundance of attractions, including unique monuments of national fine art. More than two hundred museums and galleries, including the University History Museum, the Ceramics Archaeological Museum and many others, will hospitably welcome you within their walls and familiarize themselves with the culture of this area.

Patmos is a small Greek island in the Aegean Sea, most famous for being the location of the vision given to the disciple John in the Book of Revelation in the New Testament, and where the book was written.

One of the northernmost islands of the Dodecanese complex, it has a population of 2,998 and an area of 34.05 km2(13.15 sq mi). The highest point is Profitis Ilias, 269 metres (883 ft) above sea level. The municipality of Patmos, which includes the offshore islands of Arkoi (pop. 44), Marathos (pop. 5), and several uninhabited islets, has a total population of 3,047 (2011 census) and a combined land area of 45.039 square kilometres (17.390 sq mi). It is part of the Kalymnos regional unit.

Patmos' main communities are Chora (the capital city), and Skala, the only commercial port. Other settlements are Grikou and Kampos. The churches and communities on Patmos are of the Eastern Orthodox tradition. The mayor of Patmos is Gregory Stoikos.

Ashdod is the sixth-largest city and the largest port in Israel accounting for 60% of the country's imported goods. Ashdod is located in the Southern District of the country, on the Mediterranean coast where it is situated between Tel Aviv to the North 32 kilometres (20 miles) away, and Ashkelon to the South 20 km (12 mi) away. Jerusalem is 53 km (33 mi) to the east. The city is also an important regional industrial center.

Modern Ashdod covers the territory of two ancient twin towns, one inland and one on the coast, which were for most of their history two separate entities, connected by close ties with each other. This article deals with these historic towns, including other ancient nearby sites, and modern Ashdod.

The first documented urban settlement at Ashdod dates to the Canaanite culture of the 17th century BCE, making the city one of the oldest in the world. Ashdod is mentioned 13 times in the Bible. During its pre-1956 history the city was settled by Philistines, Israelites, Greek colonists coming in the wake of Alexander's conquests, Romans and Byzantines, Arabs, Crusaders, and Ottoman Turks.

Modern Ashdod was established in 1956 on the sand hills near the site of the ancient town, and incorporated as a city in 1968, with a land-area of approximately 60 square kilometres (23 sq mi). Being a planned city, expansion followed a main development plan, which facilitated traffic and prevented air pollution in the residential areas, despite population growth. According to the Israel Central Bureau of Statistics, Ashdod had a population of 222,883 in 2017, with an area of 47,242 dunams (47.242 km2; 18.240 sq mi).

Ashdod today is home to the largest Moroccan Jewish community in Israel, the largest Karaite Jewishcommunity in Israel, and the largest Georgian Jewish community in the world.

Haifa is Israel’s third largest city. It sits on the slopes of Mount Carmel facing the Mediterranean Sea. Some call it ‘Israel’s San Francisco’.  Although traditionally a working city, there are a number of great things to do in Haifa. Be sure to cross them off your Haifa bucket list. These include the Bahai Gardens and German Colony. It also houses a number of top museums. The city is also famous across Israel for its mixed population of Jews and Arabs. Here, they peacefully coexist. The result is some amazing fusions of Arabic and Jewish cultures across the city.

Santorini, classically Thera, and officially Thira, is an island in the southern Aegean Sea, about 200 km (120 mi) southeast of Greece's mainland. It is the largest island of a small, circular archipelago, which bears the same name and is the remnant of a volcanic caldera. It forms the southernmost member of the Cyclades group of islands, with an area of approximately 73 km2 (28 sq mi) and a 2011 census population of 15,550. The municipality of Santorini includes the inhabited islands of Santorini and Therasia and the uninhabited islands of Nea Kameni, Palaia Kameni, Aspronisi, and Christiana. The total land area is 90.623 km2 (34.990 sq mi).Santorini is part of the Thira regional unit.

The island was the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption(sometimes called the Thera eruption), which occurred about 3,600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of metres deep. It may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.

It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km (310 mi) long and 20 to 40 km (12 to 25 mi) wide. The region first became volcanically active around 3–4 million years ago[citation needed], though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around the Akrotiri.
