Colegiul National Ion C. Bratianu

This school was founded in 1866, but its present facility wasn't built until 1897-98.

The architecture and decoration of the building - including the facade mosaics by Salviati - is an almost replica of the Roman Voda Lyceum (Colegiul National Roman Voda) in the city of Roman and the Unirea Lyceum in Focsani (Colegiul National Unirea).

St. Augustine's College, Canterbury

First serving as the Missionary College of the Church of England (1848 to 1947), and later as the Central College of the Anglican Communion (1952 to 1967), these buildings are now part of King's School.

Salviati made the mosaic of Christ that hung above the Warden's Chair in the college's Great Hall, which was used as a formal dining room. It was presented to the college by Dr. Henry Bailey, the school's second warden from 1850 to 1875, and was already in the room by 1882.

This may be the same mosaic the Venice and Murano Company showed at the 1880 Melbourne Expo.

It was an approximately 1/5th copy of the apse dome mosaic in St. Mark's Basilica, Venice shown below.

Above, the dining room today. However, the near wall that used to hold the mosaic cannot be seen, so it's current status is unknown.

Charterhouse School Chapel, Godalming

The original school was founded in 1611 in London by Thomas Sutton, but a Royal Commission decided to transfer it to the countryside in 1864. The first few buildings in Godalming including the chapel were designed by Philip Charles Hardwick after the boarding school moved there in 1872. Construction was carried out by Lucas Brothers.

The chapel and memorial cloister around 1900 (below). The building was not as Hardwick had originally designed it since the school's governing body decided to make it smaller, which ended up being the reason it was replaced some sixty-four years later.

The Caen marble reredos was installed in 1874 in the east end of the chapel. Salviati enamel mosaics alternated in panels with geometric shaped marble mosaics. The upper section contained a large central mosaic of the Last Supper - a gift of Carthusian G.T. Clarke, Esq. - that was the exact length of the altar. Two Evangelists on gold backgrounds flanked each side. The lower portion contained each of the Evangelists' corresponding emblems, while the central panel depicted the Sacraments - a grape vine, a dove over water, and a trefoil - and a pink cross with a white border.

In 1937, the reredos was removed and the entire east wall was blocked up, leaving just the stained glass windows visible only from the outside. The chapel was subsequently converted into the music school in 1940. The mosaic of the Last Supper came into the possession of an old Carthusian in 1942, who six years later had it restored and placed in the Memorial Chapel of Clayton Parish (St. John's) Church some 230 miles away. The reredos was rededicated in 1949. It is unknown what happened to the other parts of the original mosaic composition.

 
The new chapel at Charterhouse still in use was designed by G.G. Scott and built in 1927.
