Puerta del Sol in Madrid

The square is actually almost semi-circular in shape and owes its current form to the major renovation work carried out between 1854 and 1860.

If you look to the \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"flat\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\" south side of the semi circle you will see a clock tower, part of a building known as the \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"Real Casa de Correos\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\". This was originally built in the 18th century as part of the Post Office, and now functions as the headquarters of the President of Madrid\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s Autonomous Community.

The Puerta del Sol contains a number of well known sights both domestically and internationally associated with Spain. On the south side, the old Post Office serves as the office of the President of Madrid, the head of the regional government of the Autonomous Community of Madrid (not to be confused with the Madrid City Council, which is housed elsewhere). Also on its south side, the square holds a mounted statue of Charles III of Spain, nicknamed \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"el rey alcalde\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\" (\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"the mayor-king\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\") due to the extensive public works program he set in motion. The famous Tío Pepe lighted sign is above the square\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s eastern building between the Calle de Alcalá and the Carrera de San Jerónimo. Also on the east side lies a statue of a bear and a madrone tree (madroño), the heraldic symbol of Madrid. Until 2009, the statue stood on the north side at the entrance to Calle del Carmen. The Mariblanca (actually Venus) marks the place of a former fountain.
