James Conway Walter, A History of Horncastle from the Earliest Period to the Present Time… (1908)
“ The great feature of the reign of Stephen was the large number of castles erected by lords who were almost more powerful than their sovereign, and Adelias built her castle at Horncastle, where she resided in great state until, on her favouring the cause of the Empress Maud, daughter of the previous king, Henry I. (whereas Stephen was only his nephew) , her lands were confiscated, and, as we have already seen, only restored on condition that her castle was demolished. [21] This restoration was, however, only for life and on her demise the manor reverted to the crown. ”
