Anghiari
On map RL 12278 (Windsor Castle) Leonardo represents Anghiari, a fortified town in whose vicinity was fought the famous battle represented by Leonardo in the Council Hall of Palazzo della Signoria in Florence. An apocryphal description of the historic event is found in the Codex Atlanticus (ff. 202 a-r, 202 a-v).
Badia Tedalda
By 'Badia de' Tedaldi', Leonardo indicates the ancient abbey known as Badia Tedalda, in the vicinity of the Ravenna fortress of Cicognaia.
Caprese Michelangelo
By 'Caprese', Leonardo indicates today's Caprese Michelangelo, now considered the most probable birthplace of the great artist (as opposed to a minority who believe him to have been born at Chiusi della Verna).
Castello di Montauto

Montedoglio
Leonardo represents and indicates the stronghold of Montedoglio in the Commune of Sansepolcro.

Pieve Santo Stefano
An ancient Roman settlement, medieval castle and centre famous for such Renaissance works as its Della Robbia majolicas.
Sansepolcro
By 'Borgo a San Sepolcro', Leonardo represents with special importance the fortifications and names the city of Piero della Francesca and Luca Pacioli on map RL 12278. Further reference to Piero is found in the Codex Arundel (f. 190v), while in the Codex Atlanticus (ff. 202 a-r, 202 a-v) Sansepolcro is mentioned in an apocryphal writing for the description of the 'Battle of Anghiari'. In Ms. L (f. 2r) there is a memorandum relevant to Vitellozzo Vitelli and to a book by Archimedes 'from Borgo a San Sepolcro'. Leonardo's intellectual biography during the late 15th century and the first years of the 16th is characterised by his relationship with Luca Paioli.
