Bandar Abbas

Bandar Abbas  is a port city and capital of Hormozgān Province on the Persian Gulf. The city occupies a strategic position on the narrow Strait of Hormuz, and it is the location of the main base of the Iranian Navy.

Its current name derives from that of Shah Abbas I  (r. 1588–1629) paired with bandar – “port”.

The city was conquered by the Portuguese in 1514, and was an important location to protect their commerce in the Persian Gulf and India. They named the city Comorão, due to the presence of lobsters and crabs on its shores.

An earthquake in July 1902 damaged parts of the city, including the governor’s house and the customs office, and nearby Qeshm Island.

Mohammad Reza Shah Pahlavi paid particular attention to Bandar Abbas as a strategic port and during his time the government invested huge amounts of capital in the infrastructure.

Bandar Abbas serves as a major shipping point, mostly for imports, and has a long history of trade with India, particularly the port of Surat. Thousands of tourists visit the city and nearby islands including Qeshm and Hormuz every year.

It was a small fishing port of about 17,000 people in 1955, prior to initial plans to develop it as a major harbor. By 2001, it had grown into a major city. It has a population of 450,000 (2011 estimate).

Hormuz Island

Hormuz Island is an Iranian island in the Persian Gulf. Located in the Strait of Hormuz, 8 kilometres off the Iranian coast, the island is part of Hormozgan Province. Reddish ochre on the island and its beaches, called Golak by natives, has been exploited for artistic and culinary purposes and also attracts tourists. Degradation due to overuse of the ochre has resulted in actions by the Department of Environment to protect it.

Hormuz Island has an area of 42 km2 It is covered by sedimentary rock and layers of volcanic material on its surface. The highest point of the island is about 186 metres above sea level. Due to a lack of precipitation, the soil and water are salty. Specialists have helped cultivar white mangrove or Hara trees to grow in the climate. Due to the lack of fresh water, Iranian engineers have constructed a water pipeline from the mainland. There are many virgin beaches that go all around the island.

The island is arid, and during the summer months the temperature can rise to over 43 °C . all provisions including water had to be brought from the mainland. Its location, however, gave the island a degree of security which let it grow to be a major trading port for several centuries.

Hormuz was visited by Marco Polo, around 1290, while traveling by land, as described in his travelogue.

The Great Wall of Gorgan is a Sasanian-era defense system located near modern Gorgan in the
It is 195 km long and 6–10 m wide, and features over 30 fortresses spaced at intervals of between 10 and 50 km. It is surpassed only by the walls systems of Great Wall of China as the longest single-segment building and the longest defensive wall in existence.
The wall is located at a geographic narrowing between the Caspian Sea and the mountains of northeastern Iran. It is one of several Caspian Gates at the eastern part of a region known in antiquity as Hyrcania, on the nomadic route from the northern steppes to the Iranian heartland. The wall is believed to have protected the Sassanian Empire to the south from the peoples to the north, probably the White Huns. However, in his book Empires and Walls, Chaichian (2014) questions the validity of this interpretation using historical evidence of potential political-military threats in the region as well as the economic geography of Gorgan Wall’s environs. It is described as “amongst the most ambitious and sophisticated frontier walls” ever built in the world, and the most important of the Sassanian defense fortifications.

The cemetery was visited in 1979 and 1980 by the archeologist David Stronach. He found over 600 standing stones which are spread out in several locations.
Stronach noted two types of gravestones on the site. In both he saw “highly stylized representations of people.”
Type 1 being of a cylindrical column type with a cap-like top with heights between 60 cm to 4 m. Many of them have horizontal ribs on the shaft. Stronach interprets type 1 stones as depictions of men with their caps, helmets and in some case with clearly visible turbans, pointing to parallels in Turkic Ottoman grave-markers.
Type 2 stones are generally smaller, have rectangular sections and two opposed high-set lobes. Stronach interprets these as human shapes with arms in akimbo position.

Pigeon tower, a source of fertilizer

Pigeon tower was used as a safe house and shelter for the pigeons but this wasn’t the only function. They were built around the farms to collect their droppings as fertilizer! Every 6 month the farmers collected the dropping and used them in their farms or even they sold it. Today we know that these droppings are rich in Nitrogen, a critical element for cucurbits such as melons. No surprise that melons of Isfahan have had a reputation since 1000 years ago.
The structure includes a central cylinder which is surrounded by several smaller cylinders; all are made of brick and plaster. There are thousands of nests on the internal surface of the cylinders.
The only entrance to the tower was a set of holes on the top, just as big as a pigeon, to prevent the birds of prey from entering the tower. There is also a white stripe around the external surface of the tower which is slippery for snakes.
Pigeon towers are only found in Isfahan province and some of these organic fertilizer factories are reconstructed for the people and tourists to visit.
