ancient granite columns. The Romanesque crypt, with ancient columns, has also been restored. It has a fine paschal candlestick, and the fragments of a pulpit with marble mosaic of the 13th century. There are also preserved in the cathedral a fine Exultet roll and an of the end of the 12th century, bound in bronze decorated with gold filigree and enamels. The mosaics of the beginning of the 12th century in the apses of the cathedral and of San Benedetto, were destroyed about 1720 and 1620 respectively. The small church of San Marcello was also built in 856. In 1232–1240 the emperor Frederick II erected a castle to guard the Roman bridge over the Volturnus, composed of a triumphal arch with two towers. This was demolished in 1557. The statues with which it was decorated were contemporary imitations of classical sculptures. Some of them were preserved in the Museo Campano. The (the Campania Provincial Museum of Capua) was founded in 1870 and opened to the public in 1874. Since then it has become a cultural reference point for the whole territory and Campania. Archaeological sites Remains No pre-Roman remains have been found within the town of Capua itself, but important cemeteries have been discovered on all sides of it, the earliest of which go back to the 7th or 6th century BC. The tombs are of various forms, partly chambers with frescoes on the walls, partly cubical blocks of peperino, hollowed out, with grooved lids. The objects found within them consist mainly of vases of bronze (many of them without feet, and with incised designs of Etruscan style) and of clay, some of Greek, some of local manufacture, and of paintings. On the east of the town, in the Patturelli property, a temple has been discovered with Oscan votive inscriptions originally thought to be Oscan, now recognized as Etruscan, some of them inscribed upon terracotta tablets, the most famous of which is the Tabula Capuana, conserved in Berlin, still, after more than a century of searching, the second-longest Etruscan text. Other brief inscriptions are on cippi. A group of 150 tuff statuettes represent a matron holding one or more children in her lap: three bore Latin inscriptions of the early Imperial period. The site of the town being in a perfectly flat plain, without natural defences, it was possible to lay it out regularly. Its length from east to west
