Wikipedia
Originally the catacombs were intended only for the dead friars. However, in the following centuries it became a status symbol to be entombed into the Capuchin catacombs. In their wills, local luminaries would ask to be preserved in certain clothes, or even to have their clothes changed at regular intervals. Priests wore their clerical vestments, others were clothed according to the contemporary fashion. Relatives would visit to pray for the deceased and also to maintain the body in presentable condition.

Catacomb of Callixtus
"The Catacomb(s) of Callixtus (also known as the Cemetery of Callixtus) was one of the Catacombs of Rome on the Appian Way, most notable for containing the Crypt of the Popes (Italian: Capella dei Papi), which contained the tombs of several popes from the 2nd to 4th centuries.vThe crypt fell into disuse and decay as the remaining relics were translated from the catacombs to the various churches of Rome; the final wave of translations from the crypt occurred under Pope Sergius II in the 9th century before the Lombard invasion, primarily to San Silvestro in Capite, which unlike the Catacomb was within the Aurelian Walls."

Catacombs of Kom el-Shoqafa
"The necropolis consists of a series of Alexandrian tombs, statues and archaeological objects of the Pharaonic funeral cult with Hellenistic and early Imperial Roman influences. Due to the time period, many of the features of the Catacombs of Kom el Shoqafa merge Roman, Greek and Egyptian cultural points; some statues are Egyptian in style, yet bear Roman clothes and hair style whilst other features share a similar style. A circular staircase, which was often used to transport deceased bodies down the middle of it, leads down into the tombs that were tunneled into the bedrock during the age of the Antonine emperors (2nd century AD). The facility was then used as a burial chamber from the 2nd century to the 4th century, before being rediscovered in 1900 when a donkey accidentally fell into the access shaft. To date, three sarcophagi have been found, along with other human and animal remains which were added later. It is believed that the catacombs were only intended for a single family, but it is unclear why the site was expanded in order to house numerous other individuals. The Catacombs of Kom el Shoqafa is, according to some lists, also one of the seven medieval wonders of the world."

San Sebastiano ad Catacumbasca
"The name ad catacumbas refers to the catacombs of St Sebastian, over which the church was built, while "fuori le mura" refers to the fact that the church is built outside the Aurelian Walls, and is used to differentiate the basilica from the church of San Sebastiano al Palatino on the Palatine Hill. According to the founding tradition,[3] in 258, during the Valerian persecutions, the catacombs were temporarily used as place of sepulture of two other saints martyred in Rome, Peter and Paul, whose remains were later transferred to the two basilicas carrying their names: whence the original dedication of the church, Basilica Apostolorum ("Basilica of the Apostles")."

St. Paul's Catacombs
"St. Paul’s catacombs are part of a large cemetery once located outside the walls of the ancient Greek city of Melite, now Mdina. It also comprises the catacombs of St. Agatha, San Katald, St. Augustine and many others.
The cemetery probably originated in the Phoenician-Punic period. Like in Roman tradition, Phoenician and Punic burials were located outside city walls.[1] The many tombs discovered in areas outside the known line of the Roman city suggest that the city of Melite was close to equal size.
The early tombs consisted of a deep rectangular shaft with one or two chambers dug from its sides. This type of burial was used well into the Roman occupation of the islands, but the chambers grew larger and more regular in shape over time. It is probable that this enlargement joined neighboring tombs and led to the creation of small catacombs, which became the norm by the fourth century AD."

St. Peter's Basilica
"There are over 100 tombs within St. Peter's Basilica (extant to various extents), many located in the Vatican grotto, beneath the Basilica.

Exiled Catholic British royalty James Francis Edward Stuart and his two sons, Charles Edward Stuart and Henry Benedict Stuart, are buried here, having been granted asylum by Pope Clement XI. Also buried here are Maria Clementina Sobieska, wife of James Francis Edward Stuart, Queen Christina of Sweden, who abdicated her throne in order to convert to Catholicism, and Countess Matilda of Tuscany, supporter of the Papacy during the Investiture Controversy. The most recent interment was Pope John Paul II, on 8 April 2005. Beneath, near the crypt, is the recently discovered vaulted fourth-century "Tomb of the Julii".

"The Katyn massacre, also known as the Katyn Forest massacre (Polish: zbrodnia katyńska, mord katyński, 'Katyń crime'; Russian: Катынский расстрел Katynskij ra'sstrel 'Katyn shooting'), was a mass execution of Polish nationals carried out by the People's Commissariat for Internal Affairs (NKVD), the Soviet secret police, in April and May 1940. The massacre was prompted by Lavrentiy Beria's proposal to execute all members of the Polish Officer Corps, dated 5 March 1940. This official document was approved and signed by the Soviet Politburo, including its leader, Joseph Stalin. The number of victims is estimated at about 22,000, with 21,768 being a lower bound.[1] The victims were murdered in the Katyn Forest in Russia, the Kalinin and Kharkiv prisons and elsewhere. Of the total killed, about 8,000 were officers taken prisoner during the 1939 Soviet invasion of Poland, another 6,000 were police officers, with the rest being Polish intelligentsia arrested for allegedly being "intelligence agents, gendarmes, landowners, saboteurs, factory owners, lawyers, officials and priests."
