Divided into a series of distinctive districts, Madrid is a comfortable place to wander, and you're never far from a beautiful sight. Centro, the central district of Madrid, is where you'll find the largest concentration of sights and attractions. Take time to wander the main square, Plaza Mayor, sit back with a glass of wine and watch the people of Madrid pass by. Visit one of the many opulent churches and cathedrals in the area, like the Almudena Cathedral and be sure to take time out in Buen Retiro Park, a relaxing place perfect for slow walks. Also in Madrid’s centre, The Golden Triangle of Art is home to Museo del Prado, Museo Nacional Centro de Arte Reina Sofía, and Museo Thyssen-Bornemisza. These three museums are renowned for their collection of artistic masterpieces by European masters like Las Meninas by Diego Velázquez or Guernica by Pablo Picasso. For high-end designer shopping, head southeast to Gran Via. This ornate street never sleeps. It's a lively place with some of the most lavish buildings housing exclusive stores. In nearby El Rastro, the streets flow with regional delicacies, antiques and souvenirs at one of Spain's oldest and largest flea markets. This market takes place every Sunday.
