Follow the path straight past the Monastery, and join the Rua da Lionesa. Here a large park will be on your right, and industry on your left. Keep straight and eventually cross over the Río Leça, at which point the name of the cobbled road changes to Rua Chantre. Chantre arrives at a 4-way intersection and you should keep on straight here, which is not too clear: take the middle road, do not follow the curve in the road. Then keep on straight, with row houses on either side of you.
The road ends where it meets the Pereferica, a ring road of sorts that is tree lined and divided. Cross the pereferica and turn left to follow it. There is a trail that runs parallel to the road which you will follow, always keeping to the pereferica. It will eventually cross back over the N14 to a roundabout.
The Romanesque monastery you see today was founded by the Order of St. Benedict in the late 10th century but was built in the vicinity of a Roman Temple dedicated to Jupiter.
