Makeshift altars have been set up in the Italian town of L'Aquila, so people made homeless by last Monday's earthquake can celebrate Easter.
The Italian prime minister Silvio Berlusconi is due to attend mass in the city, where the extent of the damage has raised questions about construction standards of local buildings.
Some 20,000 people are living in tents in the Abruzzo region, where the quake killed at least 293 people.
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.
