Today this room is used as a Conference Room dedicated to the physicist Enrico Fermi, who partecipated to the courses organized by Giovanni Polvani, the director of the Physic Institute of Milan University, in 1954. A memorial tablet with dedication and a bust in a medallion, made by Giannino Castiglioni, remember his presence in the villa. It stays on the wall facing the entrance over a carved Musso marble shalf stoup.
Actually, the room is the remaining part of the XIIth century Cistercian convent church, that gave its name to the villa. The medieval church was enlarged later, after the closure of the convent established in 1567 by Carlo Borromeo because of the lack of nuns. The property was sold in 1569 to Paolo Mornico. His son Lelio, Juriconsult and podestà in Lecco, demolished the convent and built an elegant villa, that was called "Leliana" after his name. Works lasted from 1609 to 1645 and costed a lot (32.000 imperial lire). The convent church was preserved. In 1975 Lelio's successors realized a chapel dedicated to Saint Antony and used it as family vault. In 1681 they commissioned an important wooden votive tablet with a Madonna sculpture to Giovan Pietro Capiago (today it is kept in the Santa Maria Maddalena church in Varenna).
The church remained in use until 1898, when Walter Kees asked to stop its religious functions.
Still belonging to the first centuries of the church, remain part of a fresco with an intense grieved Christ in Passion dating back to the end of the fifteenth century and the women's gallery, that can be seen from the inside of the room.
The inventories of the beginning of last century do not mention the carved painted and partially goldened wooden votive tablet that actually stays at the entrance. It was placed here later, probably by De Marchi's family.
The two large vases made in carved serpentine marble, the large golden bronze chandelier, the two lamps and the red Verona marble table, that stays in the open gallery, belonged to Kees. Also belonging to him is the decorative majolica panel realized by Jackel in 1896 and placed along the wall of the near secondary stair.
