The São Sebastião Aqueduct is located in the João Paulo II Square in Coimbra. It was built around 1570 according to the desire of D. São Sebastião to transfer water from the upper city to the opposite hill. The canal is one kilometer long and thirteen meters high. The structure we see today was designed by engineer Philipe Terzi who took advantage of the presence of a Roman aqueduct to build a strong structure from the sixteenth century, and with the increase in population and cars, the arch and adjacent buildings were demolished to make way for the square and its streets, and since then, the aqueduct has preserved its The twenty arches resting on large columns with stepped faces support the canal, and have been designated a national monument since 1910.
