The sales included the well-known Marconi building near Entrecam-pos in Avenida 5 de Outubro, the bank said on Monday in a communiqué.
It also sold the Santa Maria (beside Entrecampos train station) and República 50 (in Avenida da República, beside Campo Pequeno).
The bank said it sold a total of 3,100 properties in 2017 across the country, most of which were actually outside the Lisbon and Porto urban centres, earning €338 million, 58% more than in 2016.
