"Rome marks 75th anniversary of Fosse Ardeatine massacre
22 Mar, 2019
335 people were killed at the Fosse Ardeatine in Rome in 1944.
Rome is holding several ceremonies in memory of the 335 people killed by the then occupying Nazi forces 75 years ago, on 24 March 1944.
The mass killing was in retaliation for a partisan attack on a column of marching German policemen the day before on Via Rasella, near Piazza Barberini in central Rome.
The Nazis decided that ten Italians should be executed for each German, an order soon authorised by Hitler who stipulated that it be carried out within 24 hours.
The 2019 memorial ceremonies begin on the morning of Friday 22 March with children from schools in south-east Rome suburbs walking from Piazza S. Eurosia in the Garbatella district to the Fosse Ardeatine mausoleum.
On the evening of Saturday 23 March, from 20.00 until midnight, students of the Instituto Cine Tv Roberto Rossellini will project imagery dedicated to the 335 martyrs on the Pyramid of Cestius.
At 11.00 on Monday 25 March, Italian president Sergio Mattarella will attend a wreath-laying ceremony at the Fosse Ardeatine mausoleum, which is located in the Appia Antica area.
This year will be the first wreath-laying ceremony without Rosetta Stame, the daughter of Ardeatine massacre victim and partisan fighter Nicola Ugo Stame, who died in Rome recently aged 81.
Numerous personal items belonging to the Fosse Ardeatine victims can be found in Rome's Liberation Museum on Via Tasso, a former Gestapo headquarters where Jews and resistance figures were tortured during the Nazi occupation of Rome from 1943-1944."
