The work of architect Alonso de Covarrubias, commissioned by magistrate Pedro de Córdoba during the reign of Emperor Charles V, the Puerta de Bisagra (Bisagra Gate) stands as a Renaissance Plateresque masterpiece. Constructed in 1550, it showcases an imperial shield featuring the Double-Headed Eagle, a symbol of power in Europe and America. The ensemble is crowned by a statue of the Guardian Angel, wielding a bare sword as a symbol of courage—a piece intricately carved on-site by skilled artisans.

Located on the northern facade of Toledo's city walls, the Puerta de Bisagra, also known as the New Bisagra Gate, has sparked debate regarding its origin and age. It is believed to have Arab or Mudéjar roots. In the mid-16th century, a reconstruction took place, beginning around 1540 and involving architects Nicolás de Vergara el Viejo, Juan de Benavides, Eugenio Sánchez, and Alonso de Covarrubias around 1547-1548. The construction was ultimately completed in 1576.

Comprising two independent sections, the gate boasts two lofty crenelated walls that connect, enclosing a courtyard where a statue of Charles V resides. On the external side, a voussoir arch with cushioned ashlars forms the entrance, topped by the grand coat of arms of the "Imperial City" featuring the Double-Headed Eagle. Above, an angelic guardian sculpture adorns the pediment.

Flanking this entrance are two imposing circular towers. The section facing the city includes another semicircular arched gateway, flanked by two square towers topped with pyramid-shaped roofs.
