Cornwall Street School
The building in the photo below was constructed 1860 as St. Paul's, a parochial school, but at the time of its demoliton in 2000 was commonly called Cornwall Street School.

1850s
The first mention of a school in Cornwall Street is White's Devonshire Directory of 1850; both
Ragged and Evening Schools are listed, but whether this was the same or two different buildings is not specified. They were probably one and the same building, it probably stood on the same spot as St. Paul's above, and I'm guessing it was demolished by the admiralty in 1855.
In 1856 the admiralty built a tunnel under Cornwall Street, and several surface properties along its path were demolished to make way for it. Since then no buildings have been located immediately above the tunnel - presumably because of the weight and safety factor. By 1860 the building in the above photo was constructed - St. Paul's Parochial School. It was located on the edge of the surface path of the tunnel, that path by then a lane, (being the gap between buildings in the photo) and it fronted onto Cornwall Street. My interpretation is that the church built it as a replacement for the demolished Ragged school.
1860
As with the demolished school, St Paul's newly built Parochial School was used as both a school and a mission chapel. Like so many Devonport buildings of this period it was designed by Piers St Aubyn. The plot, on the north side of Cornwall Street, was a triangular shape with the two classrooms overlooking Cornwall street and the playground at the rear tapering to the thin end bordering Cannon Street. Entrance was via the door in the side lane, which led into the playground.
Education at St Paul's was Elementary. In the beginning there were about 140 pupils, infants only. Parents had to pay a contribution to their child's education, which various writers have commented was just one penny - Cornwall Street being a poor area one penny was all that could be afforded.
1875
In 1875 Devonport School Board took over when the lease was transferred to them from the church - although the name St. Paul's was kept. The following year some internal alterations were carried out thereby increasing pupil numbers to around 200. The school continued to provide elementary level of education until after WW2.
1903
St. Paul's was renamed Cornwall Street Elementary School when control of the school was passed once again, from Devonport School Board to the Local Education Authority.
1950s
Following WW2 the school stopped taking infant pupils; it was renamed Cornwall Street Secondary Modern School for Girls.
1963
In 1963 a new secondary school was built in Devonport for both boys and girls, in Park Avenue. The girls from Cornwall Street school transferred to the new Secondary Modern and their old building closed as a school. Various groups used the property between 1963 and its demolition in 2000, including Devonport Amateur Boxing Club.
2001
The building was demolished along with the council flats in Cornwall and Cannon Street as part of the Millennium upgrade to the area.

If you wish to research further, Plymouth & West Devon Record Office hold the school records for the dates 1895 - 1963 under the reference 2312. The admission register for Cornwall Street Girls Secondary covers the period 1952 - 1963, under the reference 2312/9. Plus they hold five photographs of pupils from 1937-1938 under the reference 1597/32
