On Saturday, Pope Benedict offered a special prayer for quake survivors at an Easter eve service in St Peter's Basilica.
The Pope also sent chocolate Easter eggs to victims of the earthquake.
Easter, the most important Church feast in the predominantly Roman Catholic country, is being celebrated at makeshift venues in the area.
Conquering fear
In L'Aquila a brick from a destroyed building was blessed by a priest, along with equipment used by the emergency crews.
Services were held in many of the 67 tent cities that have been set up to accommodate the survivors.

Survivor Giovanni Diletti, 47, told AFP news agency: "It's a really different Easter after what happened. Usually I'm with my friends, but here I'm surrounded by tents."
Local Archbishop Giuseppe Molinari, who celebrated Mass in a makeshift venue north of L'Aquila, said in his homily: "I was afraid, I suffered like you. We're here to conquer that fear."
Many churches were ruined or damaged by the quake or are in areas cordoned off by the security forces as a precaution.
Some found little comfort in religion.
"Now the professionals of prayer are praying, saying Mass," said Francesco Pagani, an elderly survivor sitting in one of the emergency camps.
"Everybody prays... and yet Jesus Christ sends us an earthquake."
Prime Minister Silvio Berlusconi went to L'Aquila to attend Easter Mass.
Months of uncertainty
The local chief prosecutor has set up an inquiry to see if there is any criminal blame for the number of collapsed buildings.

Some rescuers have spoken of the ease with which they sawed through concrete blocks and the investigation will look at whether the correct mix of sand and concrete was used in their construction.
One estimate values the earthquake damage at up to 3bn euros ($4bn) but the impact on Italy's economy, already hit by recession, is expected to be limited, Reuters news agency reports.
About 40,000 people are homeless of whom some 15,000 have found shelter in hotels or private homes.
The authorities have said it could be weeks, if not months, before it is known which of the houses left standing are safe enough to be repaired and which will have to be demolished.
