St. Leonard’s Church

St. Leonard’s Church, Boston (1885)

St. Leonard’s Church is a Roman Catholic church located at the corner of Hanover and Prince Streets in the north end of Boston. Founded in 1873 and completed in 1899, it is one of the oldest churches built by Italian immigrants in the United States. Construction of the current building, designed in the Romanesque style by architect William Holmes, did not begin until 1885. The church is a pending Boston landmark building.

With no access to the attic or behind the walls, approximately 3000 square feet of deteriorated plaster on wood lath on the dome and walls were consolidated from blind locations using the HPCS Remote Consolidant Applicator. The work was successfully performed by Historic Plaster Solutions, an affiliate of John Tiedemann Inc./HPCS USA.

Upon completion of the plaster restoration and consolidation, John Tiedemann Inc. conducted interior painting, decorative painting, art restoration, faux finishing, gilding, and glazing. The church may be well over 100 years of age but this restoration program returned it to its original glory.
