Recently while wandering through the city center, I suddenly realized I didn’t know much about these streets I pass by every day. I decided to spend some time researching Madrid’s city center history, and discovered it’s quite fascinating—I’d like to share it with you all.
The Origin of Puerta del Sol
Puerta del Sol is probably one of Madrid’s most famous locations. The name actually comes from a 15th-century city gate that stood here, decorated with a sun motif. The current square was redesigned in the 19th century, and the famous “Kilometer Zero” marker is located here—all road distances in Spain are calculated from this point. The equestrian statue of Charles III in the square wasn’t placed there until 1994, much later than most people imagine.

Route from Puerta del Sol to Plaza Mayor
The walk from Puerta del Sol to Plaza Mayor takes only 5 minutes, but the buildings along this route are quite impressive. Most buildings on both sides of Calle Mayor were constructed in the 17th-18th centuries, during the transition period between the Madrid’s glorious historical achievements Habsburg and Bourbon dynasties. The street isn’t wide, but the buildings are tall—typical old quarter style.
| Location | Construction Period | Main Features |
| Puerta del Sol | 19th century renovation | Kilometer Zero marker, Charles III statue |
| Calle Mayor | 17th-18th centuries | Habsburg period architectural style |
| Plaza Mayor | Completed 1619 | Philip III statue, arcade architecture |
| San Miguel Market | 1916 | Iron structure market |
The Story of Plaza Mayor
Plaza Mayor was completed in 1619 during the reign of Philip III. Originally an irregular open space, it was later transformed into the enclosed rectangular square we see today. The square has survived three major fires, and the current buildings mainly date from the last reconstruction in 1790. This place has witnessed bullfights, criminal executions, and religious ceremonies—now it’s primarily a tourist gathering spot. On weekends it’s so crowded you can barely move.
It’s worth noting that many small alleys around Plaza Mayor lead to other areas. For instance, Calle de Cuchilleros leads to the Latin Quarter, where you’ll find many traditional restaurants and bars. If you want to avoid tourists, venture into those alleys to better experience the atmosphere of old Madrid.
Practical Tips
If you want to properly explore this area of Madrid’s historic center, I recommend going on weekday mornings when there are relatively fewer tourists. Restaurants near Plaza Mayor are generally expensive, so walk a bit further to the Latin Quarter or Lavapiés neighborhood for better value. Additionally, while San Miguel Market is famous, it’s also pricey. If you just want to buy some food for Madrid’s historic parks, the small shops nearby are actually more affordable.
