The church of S.Agostino in L’Aquila was built at the beginning of XVIII century, replacing an older church collapsed during the strong earthquake of 1703. The building has a central layout. During April 6th earthquake, it suffered many damage. The lantern collapsed. Severe cracks concerned the hall-drum-dome elliptical system, the apse and the bell tower. Moreover, the façade was subjected to an overturning mechanism. The elliptical layout of the building induced a mainly longitudinal seismic response. In the paper, a extensive description of the damage is provided. Moreover, the seismic behavior of the church is discussed on the basis of observation of damage and vulnerability features of the structure. A correlation between damage, vulnerability and seismic actions is finally proposed.
