Notre Dame Cathedral is a harmonious combination of Roman architecture and late medieval Gothic features. The most unique features of the Church – the two 60-meter high bronze bell towers – were added years following original construction in to magnify the Church’s beauty. Until now, the Church still remains in a near-undisturbed original state due to the special bricks used in its construction: they were originally created in France and shipped directly to Vietnam.

Constructed around the Church of the Holy Sepulchre, in the north-western part of the Old City, the area is home to several Christian sights. Few houses can be found here — it's mostly about religious buildings, educational facilities, and a plethora of cafés, restaurants, and shops. The streets are packed with vendors. It is especially worth exploring the area of Mauristan, teeming with shops and colourful stalls. Used as a market during the Roman Empire, the area hosted churches and hospices during the Crusades (in Persian, "Mauristan" means hospital).

This mill is one of at least 10 hydraulic constructions erected along the "Ribera de los Molinos" (The Mills Riverbank) in the 16th century. This building, popularly known as The Wide Mill, is one of the best preserved sections of this waterway and offers visitors a chance to learn about its architecture and history.
