The Old Jewish Cemetery was established in the first half of the 15th century. Along with the Old-New Synagogue, it is one of the most important hictoric sites in Prague´s Jewish Town. The oldest tombstone, which marks the grave of the poet and scholar Avigdor Karo, dates from the year 1439. Burials took place in the cemetery until 1787. Today it contains some 12,000 tombstones, al though the number of persons buried here is much greater. The cemetery was enlarged a number of times in the past. In spite of this the area did not suffice and earth was brought in to add further layers. It is assumed that the cemetery contains several burial layers placed on top of each other. (more info)
