The Guaranty Building at Church and Pearl streets in Buffalo is an architectural gem.

The Guaranty Construction Co. was originally the contractor for Henry Taylor, who commissioned the building but died in 1894 just as plans and funding were in place to build the building. Guaranty took over the project and completed the building. In 1900 the building was renamed the Prudential Building, however many references to Guaranty remain.
