The Bridge of Mantible (Puente Romano de Mantible) is a ruined bridge located near Logroño. According to some historians, construction of the bridge began in the first half of the 2nd century, well into Rome's imperial period. Others suggest that the bridge was built in the 11th century, near the same time in which the Puente La Reina was constructed over the River Arga, and that both were made to join the two most important cities of the Kingdom of Navarre, Nájera and Pamplona.
Neither theory makes clear at what point the bridge became no longer passable, but there are documents that suggest that it had already fully deteriorated by halfway through the 16th century.
The bridge is 164 meters long, 5 meters wide and reaches a maximum height of 30 meters. It was built with seven semicircular arches, only two of which stand relatively intact today. There are only a few remains of the other five arches. The two standing arches serve as an example of the excellent quarry stone used in the bridge.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
