From the Caracara Accommodation you can be at Entroncamento mainline rail station in 10 minutes and from there take the Intercity express to have you in the heart of Lisbon in just 54 minutes. Lisbon is consistently voted one of the best cities to visit and in 2010 was voted number 1 European Leading City Break Destination. There are many things to do and places to see in the city and many of these can be taken in during a one day visit provided you do your homework in advance and prepare an itinerary. Here is some information on visiting Lisbon. The following are a few of the attractions that the city has to offer:   Oceanarium These first two photos show the largest Oceanarium in Europe. It can easily be reached on foot from Oriente station and stands in the Parque das Nações. The site has four separate biotypes, each recreating one of the world's coastal habitats. The site is said to resemble an aircraft carrier and has around 16,000 exibits from 450 species including sharks, barracuda, tuna and rays. Current entry fee (July 2011) is €12 for an adult and 4-12 year olds €6, under 3's are free and family tickets are available at discounted rates.     Jeronimos Monastery Construction of the Mosteiro dos Jerónimos was started in 1501 and funded by treasures captured in Africa, Asia and South America. It is undoubtedly one of the finest examples of the Manueline style of architecture, a style considered to be unique to Portugal. Other sites to visit to see this style of architecture are the Convento de Cristo in Tomar and the Abbey in Batalha       It was built as a symbol of gratitude to the Virgin Mary for the success of Vasco de Gama's voyage of discovery to India but also stands as an everlasting monument to the Age of Discovery. The monastery contains the tombs of many of the most important people in Portugal's history including royalty and Vasco de Gama. Very close to the Monastery's main entrance can be found the Maritime Museum, where you will find amongst many other exhibits, two 18th century ceremonial barges built for royalty and the sea plane "Santa Cruz" - famous for making the first crossing of the South Atlantic in 1922.      Torre de Belém Close to the monastery is the magnificent Tower of Belém. Originally built as a fort in the middle of the Targus river it now stands on the edge of the river and is a must see site for visitors to the city.         Tram 28  One of the most symbolic sounds of Lisbon is the clanging of the electric trams as they circumnavigate the city. Many of them are modern nowadays but there are still a few of the originals running and these include the no.28, which winds its way through the cobbled streets and hills of the old town. Be careful though, as pickpockets have been known to target tourists using them and also be aware that there is no air-conditioning unless you count an open window and many people find the ride quite claustrophobic. One of the best places to view the city is from St. George's Castle, which can be reached by travelling on the no.28 but why not enjoy the walk up the hill to the viewpoints and castle!     Yellow Sightseeing Open Top Bus  This is one of our top tips for getting around the various visitor sites whilst also enjoying a leisurely chauffered drive through the city. There are several different routes to choose from and tickets to buy.     You can stay on board for a 2.5 hour ride or you can simply hop off at your chosen site before getting back on and resuming your journey when you wish.
