Spain's capital city, Madrid boasts an impressive array

Opened by Queen Sofía in 1986, the Museo Nacional Centro de Arte Reina Sofía is Madrid's avant-garde center for contemporary art. The sleek modern building was created by the architect Antonio Fernández Alba and has features that recall the Pompidou Center in Paris, especially the three glass towers that house the elevators on the outside of the building.

Another wonderful surprise to visitors is the charming garden in the inner courtyard filled with imaginative sculptures.

Not all of Madrid's tourist attractions revolve around art. One of its most-visited museums draws football (soccer) fans to the stadium known as Estadio Santiago Bernabéu, the home of the Real Madrid soccer club. The club boasts unapologetically that their stadium is the "Greatest Stadium in the World."

You can take a tour of the stadium, as well as the museum, which displays trophies, team artifacts, and temporary exhibits. Tours also give fans a chance to enjoy the view of the field from the top of the stadium.

The Thyssen-Bornemisza Museum presents an overview of European art from the 17th century to the late 20th century. With nearly 1,000 paintings on display, the collection covers medieval religious art, Renaissance-era portraits and biblical themes, the Baroque period, Rococo, Romanticism, Impressionism, Fauvism, Expressionism, modern art, and Pop Art. The museum also has an excellent collection of 19th-century American paintings.

This prestigious collection includes renowned masterpieces such as Christ and the Samaritan Woman by Duccio di Buoninsegna, Venus and Cupid by Peter Paul Rubens, The Annunciation by El Greco, Young Knight in a Landscape by Vittore Carpaccio, Jesus among the Doctors by Albrecht Dürer, The See-Saw by Jean-Honoré Fragonard, Dancer in Green by Edward Degas, Solitude by Jean-Baptiste-Camille Corot, Route de Versailles by Camille Pissarro, Les Vessenots in Auvers by Vincent van Gogh, and The Harvesters by Pablo Picasso.

The Puerta del Sol was named after the sun emblem on the old city gate, which formerly stood here. This spacious town square aligns with the rising sun. Besides being a hub of public transportation (with several bus stops and Metro entrances), the Puerta del Sol is also the "Kilometer Zero" point from which all distances on the Spanish national road network are measured.

The Puerta del Sol has been the scene of many historic events, including the Spanish resistance to Napoleon on May 2nd, 1808, and in 1931, the Second Republic was proclaimed here.

This elegant 17th-century plaza was built during the reign of Philip III and used as a center of commerce and municipal life, as well as the scene of ceremonial events such as the proclamation of a new king and the canonization of saints. The square also served as a venue for bullfights, dramatic performances, and knightly tournaments.

The Plaza Mayor took on its present appearance after a fire in 1790, when the corners were enclosed and the nine entrance arches were constructed, linking it to Calle de Toledo, Calle Mayor, Calle de Postas, and others.

A masterpiece of Rococo style, the Salón del Trono (Throne Room) is adorned with frescoes by Tiepolo including The Greatness of the Spanish Monarchy, one of his finest works. Still used for State ceremonies, the Throne Room is clad in sumptuous red velvet and decorated with valuable tapestries, mirrors, furniture, and chandeliers.

History buffs will want to visit the palace's Royal Armory (La Real Armería), which contains 3,000 exhibits dating back to the Middle Ages. On display are the armor and weapons that have been used by Spain's kings over the centuries.

This grandiose palace is the Spanish version of Versailles, a royal court designed to impress. However, unlike Versailles, which is now just a museum, the Royal Palace of Madrid (Palacio Real de Madrid) is still the official residence of a monarch (the King of Spain) and continues to be used for official State events.

The palace was commissioned by Philip V in the 18th century. The majestic Neoclassical facade is crafted entirely from granite and white Colmenar stone. The facade's Ionic columns and Doric pilasters are based on drawings that the sculptor Bernini originally intended for the Louvre in Paris. The balustrade features statues of Spanish kings.

Built in 1887, the Palacio de Cristal (Crystal Palace) is a splendid cast-iron and glass pavilion that presents exhibitions of contemporary art. The Crystal Palace looks out onto a graceful fountain and reflecting pool. Visitors will find other interesting fountains at Buen Retiro Park including Los Galápagos (The Turtles), El Ángel Caído (The Fallen Angel), and La Alcachofa (The Artichoke).

Locals and tourists alike enjoy boating on the park's tranquil lake. Other favorite things to do include taking the kids to puppet shows at the Teatro de Títeres, going for walks on the scenic tree-lined paths, and basking in the sun or relaxing in the shade at one of the park's outdoor cafés.

The Buen Retiro Park (Parque del Retiro) is an oasis of peace in the heart of Madrid. This lush and beautifully manicured park offers an escape from the hustle and bustle of the city. The park encompasses more than 125 hectares and is shaded by over 15,000 trees.

Created for the Count-Duke of Olivares in the 17th century, the historic park has an elegant ambiance with its variety of gardens and tree-lined paths. The Parque del Retiro was owned by the Spanish royal family until the 19th century; since then it has been a public park.

After touring the art collection, tourists can relax at the Real Jardín Botánico (Royal Botanical Garden) located next to the Prado Museum. This lovely green space features shady pathways, benches, sculptures, greenhouses, a Kitchen Garden planted with vegetables, and a Rose Garden that blooms in May and early June. The Real Jardín Botánico is also home to the Museum of Natural History.

About a 10-minute walk from the Real Jardín Botánico is the popular Restaurante TriCiclo (28 Calle Santa María), which serves lunch and dinner in a contemporary-style dining room with a casual ambience. The restaurant specializes in international cuisine, prepared from seasonal market ingredients with gastronomic flair.
