Santa Maria Annunciata in Chiesa Rossa

The construction started by Franco Della Porta in Romanesque Revival style, and was completed in 1932 by Giovanni Muzio.

Muzio has designed the church in plan as Latin cross, the central nave is covered by Barrel vault and ends in the Apse.

The Baptistery, in the left in a lateral chapel, has an octagonal shape and contains San Giovannino a sculpture by Giacomo Manzù.

The design was completed two days before Flavin's death on November 26, 1996 and installed a year later.

The installation is made with green and blue fluorescent lights for the main nave, red in the transept and yellow for the apse.
