We continue along Valle Inclán Street, until reaching San Roque Street, site of the old Baroque Hospital, with a beautiful porch and cloister, next to the old Porta da Pena, through where we enter the old town. We then walk down Algalia de Arriba Street, which once contained most of the student residences until well into the twentieth century. On reaching number 27 we find a thirteenthcentury Gothic tower on four floors with a majestic air, which includes decorative elements in some of its windows. We then turn left into the alleyway known as the Calella dos Truques, and then onto Algalia de Abaixo Street, an area with a lively nightlife together with the neighbouring streets. At number 29 we find the oldest house in the whole city, dating from the eleventh or twelfth century, a fine example of mediaeval architecture with overhanging floors. In front of it is the Baroque Amarante mansion. We are now traversing the most traditional part of Compostela: Entremuros, Oliveira Street and the Irmáns Gómez Square, finally arriving at the doors of the church of Santo Agostiño, missing a tower that was demolished by lightning in the eighteenth century.
