The Bridge of Toledo unites the banks of the Manzanares River and connects the Pyramid Square with Marques de Vadillo Square. The idea for constructing a bridge in this very spot originated in the 17th Century. It was then that the ruling king Felipe IV decided it would be a good idea if the ever-expanding city of Madrid had a more immediate access to the route leading towards the city of Toledo. The original bridge was constructed in the mid-17th Century. Unfortunately, a flood destroyed it soon after its completion.

Within a decade, plans for its reconstruction were in full swing. The new bridge was completed in 1684 by the architect Teodoro Ardemans. In the early 18th Century, its decoration was remodelled to suit popular trends. Figures of the patron saint of the city, San Isidro, crafted in 1735 by Juam Rum, were placed in the central part of the bridge.
