This annual public holiday has been celebrated since 1338 and commemorates the date in 1238 when King James I of Aragón entered the city, freeing it from Moorish rule. In the week leading up to the 9th there are free concerts and parades around town, including a correfoc ('fire-running') which takes place on the preceding Saturday evening in the El Carme district. During this same weekend nine governmental palaces which are ordinarily closed to the public are opened for general visitation (Sa and Su 10:00-20:00, free admission). Of these the 15th-century Gothic Palau de la Generalitat (Palacio de la Generalidad / Palace of the General Assembly) is the most remarkable, and is well worth the long queue to see the well-preserved interior.
Formal festivities commence at midnight on 8 October with a fireworks display from the Túria River park by the Pont de l'Exposició (by Alameda metro station). At noon on the following day a formal procession carries the Valencian flag from the Ayuntamiento (City Hall) to the Jardí del Parterre (Parque del Parterre / Parterre Park), where a wreath is laid before the equestrian statue of King James.
The highlight of the 9th itself is the parade of Moros i Cristians (Spanish: Moros y Cristianos), which commences at Plaça d'Alfons el Magnànim and proceeds down Carrer de la Pau and Carrer de Sant Vicent, finally terminating at Plaça de l’Ajuntament. The parade starts at 18:30 but it is best to find a spot about a half-hour before the parade begins.
The 9th of October is also the day of St. Dionysius, which for Valencians is similar to Valentine's Day. In a tradition dating to the 18th century, it is customary for men to give their sweethearts a mocadorà – a small bundle of marzipan treats shaped like fruits and wrapped in a handkerchief. Beginning a week before the 9th, these can be purchased at pastry shops and even some supermarkets.
Museo de las Ciencias Príncipe Felipe / Príncipe Felipe Science Museum
A science museum designed to resemble a whale skeleton, it has interactive exhibits on three floors.
The largest oceanarium in Europe, and the second-largest in the world, has seven sections devoted to different ecological zones. The building was designed by Félix Candela to resemble a water lily. Highlights include a dolphinarium, a walk-through shark tunnel, a shark tank (open for public diving), and spherical bird aviary. There are several restaurants on-site, and with so many attractions it’s easy to make this into an all-day affair.
A botanic garden landscaped with plants native to Valencia. The park also has the Jardí d'Astronomia (Jardín de la Astronomía / Astronomy Garden) and the Passeig de l'Art (Paseo del Arte / Art Promenade), which has permanent and temporary exhibits of large-scale contemporary art, mostly sculpture.
A multi-use covered plaza, designed for sporting events, concerts, and special exhibits.
Puente de l'Assut de l'Or / Assut de l'Or Bridge
The striking cable-stayed bridge designed by Santiago Calatrava and completed in 2008, crosses the dry Túria riverbed. At 125 m high, the bridge tower is the highest point in Valencia.
La Seu / Valencia Cathedral
It was the site of a Roman temple, then a Visigothic cathedral, and then a Moorish grand mosque. It is now the seat of the archbishropic of Valencia. The current Gothic structure was begun in 1262 and remodeled numerous times, resulting in a structure with elements from three distinct architectural periods. Especially notable are the Puerta de los Apóstoles from the 14th century, and the Puerta del Palau, the oldest doorway of the cathedral, which is Romanesque with Moorish influences.
