This impressive conservatory with its Victorian characteristics was designed and erected by Boyd and Son of Paisley, Scotland, dismantled into sections and transported to Port Elizabeth where it was re-erected under the supervision of Mr Frazer of Boyds. The building was officially opened by John X Merriman on 12 September 1882. The conservatory was named after Mr H W Pearson, Mayor of Port Elizabeth from 1871 to 1896.
