The economy within Torres Novas continued along the 19th century, with some successes and failures: the founding of the "Fábrica de Papel do Almonda" (1818); establishment of the "Companhia de Fiação de Torres Novas" (1845); the creation of the transporter "João Clara & Companhia (Irmãos) Lda." which, at the time of its nationalization (1975), was domianted by "Clara Transportes - S.A.R.L.". In 1835, Queen Maria I of Portugal would donate the Castle to Torres Nova's municipality, which would decide to demolish parts of the structure.
