The Tower of Pisa is the churches belltower. The city of Pisa was at the beginning a simple but important Italian seaport. With its growth, so did its religious buildings.
Its fame and power grew gradually over the years, as the people of Pisa were involved in various military conflicts and trade agreements.
The Pisans attacked the city of Palermo on the island of Sicily in 1063. The attack was successful and the conquerors returned to Pisa with a great deal of treasure.
To show the world just how important the city was, the people of Pisa decided to build a great cathedral complex, the Field of Miracles. The plan included a cathedral, a baptistery, a bell tower (the Tower of Pisa) and a cemetery.

I’m writing from the most beautiful and incredible place in the world that I have ever seen during my 15-year career as a travel writer in more than 70 countries. I’m writing to you from Ha Long Bay in Vietnam.

There is a saying that if you have not visited Ha Long Bay you have not yet been to Vietnam. I say that if you have not visited Ha Long Bay you have not yet seen the most beautiful place in the world.

180 km from Hanoi City, towards the northeast, it takes around 4 hours by bus due to the speed limit, and then you will arrive to Ha Long City and the wonderful Ha Long Bay.

1969 limestone islands of various shapes, sizes, and in different green and amazing colors rise above the sea level in an area of more than 1,500 square kilometers that creates this World Heritage site. Ha Long Bay still retains its historical and culture values.

The guide told me that Ha Long Bay has been twice recognized by UNESCO as a World Heritage Site in 1994 and 2000, and also that Ha Long Bay is in second place in the worldwide competition of the World’s Seven Natural Wonders. I told him that before all, God has given the Vietnamese people this wonder for their kindness.

Ha Long Bay is as attractive and beautiful throughout the four seasons: spring, summer, autumn, and winter. Traveling on small sailboats among hundreds of limestone islands, one may visit the amazing Surprise Cave, the floating fishing village, and see how the locals live are top of the list of things to do here. On Titop Island, one may swim and relax on the beach or enjoy a kayaking program to the nearby Luon Cave and much more.

And what about the important question of where to sleep? Syrena Cruises and other cruises are offering wonderful programs. A luxury cruise from the harbor and across Ha Long Bay, has 34 luxury cabins and suites each with a balcony, as well as restaurants and a meeting room on the 3rd deck. Travelers may experience Asian or Western cuisine, precisely sea food, and also have a session with a massage therapist, unwind in the sauna, take a sunbath and relax on the expansive deck, experience squid fishing, movie night, and a cooking demonstration.

Other attractions during your stay in Ha Long, beside exploring Ha Long Bay itself, if to visit the Royal Park in Halong City, Water Music, a circus performance by dolphins, sea lions, crocodiles, and much more.

The experience of visiting Ha Long Bay is unforgettable, where you will see something that will stay in your mind and eyes for years. You will enjoy meeting Vietnamese people and tasting their delicious food, you will have fresh air all day and night, especially if you wake up early in the morning and watch the sun rise on the deck coming slowly through the islands.

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia.

The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coralpolyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.

A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as fishing and tourism. Other environmental pressures on the reef and its ecosystem include runoff, climate change accompanied by mass coral bleaching, and cyclic population outbreaks of the crown-of-thorns starfish. According to a study published in October 2012 by the Proceedings of the National Academy of Sciences, the reef has lost more than half its coral cover since 1985.

The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups' cultures and spirituality. The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. Tourism is an important economic activity for the region, generating over AUD$3 billion per year. In November 2014, Google launched Google Underwater Street View in 3D of the Great Barrier Reef.

A March 2016 report stated that coral bleaching was more widespread than previously thought, seriously affecting the northern parts of the reef as a result of warming ocean temperatures. In October 2016, Outside published an obituary for the reef; the article was criticized for being premature and hindering efforts to bolster the resilience of the reef. In March 2017, the journal Nature published a paper showing that huge sections of a 800-kilometre (500 mi) stretch in the northern part of the reef had died in the course of 2016 due to high water temperatures, an event that the authors put down to the effects of global climate change.
