(n. 2), the last image with medieval walls. On the exterior: n. 1 San
Simplicio, numbers 3–4 Sant’Antonio and Santa Maria del Mare,

between the Cabuabbas spring and the city. (State Archive of Turin,
Sez.Riun., Uff. Gen Fin., Tipi (sez.II), Terranova, m.233).
It is possible that the new medieval city recovered some preexisting structures
of Olbia, such as parts of the Roman roads, but did not bear any urban con-
nection to the ancient plan (Figs 19.18–19.19). Terranova’s medieval port was
built by the intentional sinking of some ships during the years of the city’s
founding. Recent archaeological excavations have revealed that the resultant
advance of the coastline allowed builders to design the new port within the
realizzazioni,” in Guidoni, Città nuove medievali, pp. 9–17. Cadinu, “Olbia: una Terranova
medievale” (2008), p. 149.
