At the corner near the campanile, this (west) side is occupied entirely by the Biblioteca (Library) designed by Jacopo Sansovino to hold the Biblioteca Marciana (library of St Mark). Building started in 1537 and it was extended, after the death of Sansovino, by Vincenzo Scamozzi in 1588–91. The building was said by Palladio to be "the most magnificent and ornate structure built since ancient times".[2] The arcade continues to the end of the building with cafés and shops and also the entrances to the Archaeological Museum, the Biblioteca Marciana and the National Library, which occupy the floors above.[citation needed]
