Renowned for its craftsmanship of marble, bronze, alabaster, and stone sculptures and mosaics, the gallery specialises in reproductions of Classical, Neo-classical and Renaissance art, while also producing original works by contemporary artists.

The first mention of the gallery appears in 19th century city guidebooks, which describe its location in the current Palazzo Corsini, as a "space with a large window on the Lungarno with a sculpture atelier in the rear with access from Via del Parione".

In 1840 he was nominated by the academy "Academician Professor of Sculpture in the First Class of the Arts and Design".In 1834, Niccolò sculpted the plastic decoration of the palace that the publisher Vincenzo Batelli had built in 1831–1832 in via Sant'Egidio at number 12.

The public subscription made to finance the transaction was unsuccessful, leading Niccolò Bazzanti to complete only the statue of Andrea Di Cione (Orcagna).
