Florence's Palazzo Capponi alle Rovinate was built on his behalf in the first half of the 15th century (completed in 1426) by Lorenzo di Bicci, who always carried out Niccolò's wishes, including those for frescoes and a painting for the Church of Saint Lucia dei Magnoli, which though documented are now lost.
Rinaldo degli Albizzi, a Florentine politician who was openly against the political rise of Cosimo de' Medici was held in check by Niccolò da Uzzano as long as he lived.
In the Bargello Museum in Florence, there is a polychrome terracotta bust of Niccolò, attributed to Donatello, dated to around 1432, which might make it the earliest example of this format of Florentine portrait bust.[1]
