A large part of the Gothic fortifications of Prague-New Town are hidden below today's city surface, with archaeology remaining the main source for learning more about them. The New Town wall from the period of Charles IV was first discovered in Sokolská St. in 1969.
A short section of the wall was uncovered in 2011 in Božena Němcová St. in the southeast vicinity of the Church and Convent of the Virgin Mary and St. Charles the Great.
In connection with the reconstruction of Baroque bastion XXXI, sections of the Gothic wall between Na Slupi and Karlov were gradually subjected to archaeological investigation and, starting in 2001, preserved. Attention is also paid to the ends of the New Town fortifications at Na Poříčí and Na Slupi, where scholars have different ideas about their appearance.
