Top Attractions of Rome Piazza Navona Navona Square

Piazza Navona is one of the most famous and arguably the most beautiful of Rome's many squares. The large and lively square features no less than three magnificent fountains. Another eyecatcher is the Baroque church of Sant'Agnese in Agone.

The square is built on the former Stadium of Domitian, built by Emperor Domitian in 86 AD. Hence the long, oval shape of the square. The stadium, which had a larger arena than the Colosseum was mainly used for festivals and sporting events.

The stadium was known as 'Circus Agonalis' (competition arena). It is believed that over time the name changed to 'in agone' to 'navone' and eventually to 'navona'.

In the fifteenth century the stadium was paved over to create the Navona square, but remnants of Domitian's stadium are still visible around the area. Guided tours to this underground monument are available, they start at Piazza Tor Sanguigna 13.

Fountain of the Four Rivers

The main attraction of Piazza Navona is the trio of fountains that adorn the square. The central and largest fountain is the Fontana dei Quattro Fiumi (Fountain of the Four Rivers). It was constructed between 1647 and 1651 on request of pope Innocent X.

The design of the fountain was first commissioned to Borromini, but it was ultimately handed to his rival Bernini. The fountain features four figures, each representing a river from a different continent - the Nile, Ganges, Danube and Rio de la Plata. The statues are at the base of a rock supporting an obelisk, originally located at the Circus of Maxentius, near the Appian Way.

Neptune Fountain & Moor Fountain

The two other fountains on the piazza are the Fontana del Nettuno (Neptune fountain) at the northern end and the Fontana del Moro (Moor fountain) at the southern end of the square.

The Fontana del Nettuno, also known as the Calderari, was built in 1576 by Giacomo della Porta. The statues of Neptune surrounded by sea nymphs were added in the nineteenth century.

Giacomo della Porta also built the Fontana del Moro. The central statue of a Moor holding a dolphin, a design by Bernini, was added in the seventeenth century. The tritons are nineteenth-century additions.

Church of Sant'Agnese in Agone

Another highlight at Navona square is the church of Sant'Agnese in Agone. It was commissioned in 1652 by Pope Innocent X and built on the site where according to legend, St. Agnes was stripped naked, but miraculously saved from disgrace by extraordinary growth of hair.

The front facade of the Baroque church was designed by Borromini, Bernini's main rival. Construction started just two years after the completion of Bernini's Fountain of the Four Rivers, right in front of the building. The church was completed in 1670.

Location

The Piazza Navona is situated in the historic center of Rome, west of the Pantheon. It is one of Rome's liveliest squares, with many outdoor cafes, restaurants and night clubs in the neighborhood.

Top Attractions of Chicago Sears Tower

At the time the Sears tower was constructed in 1974, it was the world's tallest building, eclipsing New York's twin-towered World Trade Center by 25 meters (83 ft). It would keep the title of tallest building in the world until the Petronas twin towers in Kuala Lumpur, Malaysia were constructed in 1997.

The Tallest

There was much discussion on whether the Petronas Towers are actually taller than the Sears Tower as the height of the antennas on the Petronas Towers are included in the total height, while the height of the antennas are not included in the height calculation of the Sears Tower as they are not considered an actual part of the building.

With the construction of the 508 meters tall Taipei 101 in 2004 this discussion became irrelevant. However, when in November 2013 New York's One WTC was officially declared taller than the Sears Tower - grabbing the coveted title of the tallest building in the US, the issue was brought up once again: one WTC's rather pathetic spire was included in the calculation of its height, so that even though the Sears Tower's roof is a substantial 25 meters (83 feet) higher than One WTC's, the latter is now officially 99 meters (325 ft) taller.

Anyhow, the Sears tower is still the tallest Chicago skyscraper, exceeding the height of the number two, the Trump International Hotel and Tower by 27 meters (89 ft) and the Aon Center by 96 meters (315 ft).

The Structure

The building consists of nine framed tubes, which are actually nine skyscrapers on themselves taken together into one building. Originally, the plan included no less than fifteen tubes, but when the planned hotel was 
  taken out of the project, only nine tubes were used in the final designs. The nine tubes all reach forty-nine stories. At that point, two tubes end. The other rise up to the sixty-fifth floor. From the sixty-sixth to the ninetieth floor, the tower has the shape of a crucifix. Two tubes, creating a rectangular, reach the full height of 442 meters (1451ft).

Wind Load

The result is an interesting tower, which looks different from all angles. The construction, designed by Fazlur Kahn (1929-82), has other advantages : the construction with separate tubes provides lateral strengths to withstand the strong Chicago wind loads, as each tube only needs to take a part of the pressure.

Observation Deck

The Sears Tower's observation deck - known as the skydeck - is one of Chicago's most popular attractions. At 1,353 ft or 412 m, it's Chicago's

highest observatory, besting the John Hancock Center's by 323 ft (98m).
The most spectacular attraction at the skydeck is 'the ledge', a glass balcony extending 4.3 ft where you can look straight down. It will make most people feel uneasy at first but the balconies offer spectacular views over Wacker Drive and the Chicago River.

Willis Tower

The tower was named after Sears, Roebuck and Co., an American chain of Department Stores which was headquartered here. Sears sold the building in 1993 after moving to the suburbs. The building's name was left unchanged until Juli 16, 2009, when it was renamed Willis Tower for one of the skyscraper's tenants, a British insurance firm. The move was met with local opposition however, and some even started online petitions to protest the name change.
