Pamplona is famous for its unique religious monuments, where the Church of St. Nicholas is of particular interest. Built in the 12th century, today the ancient church looks more like a medieval fortification rather than a classical religious monument. The main feature of the church is its old Gothic-style interior. Its walls also keep an old baroque organ, which is considered the city's main organ.
A 13th-century religious monument is the Church of San Saturnino, which had been used as a fortress for many centuries and took part in many battles. This church has very powerful thick walls, which allowed the building to survive hundreds of years later. The main secret of this church is a spring located at its entrance. According to legend, the Holy Saturninus, after whom the church was later named, baptized the first Christians in the city in this spring.
Pamplona can offer a great planetarium, the official opening of which took place in 1993. The planetarium housed in a very beautiful building of cylindrical shape is the main attraction of the picturesque Yamaguchi Park. The planetarium hosts many interesting exhibitions; all kinds of thematic events are held and documentaries about space are shown here every day.
