The scenic Instituto, located in Várzea, 11km west of central Recife, contains a massive collection of European and Brazilian art, swords, armor and historical artifacts, all set in a fake medieval castle on lovely grounds. It's best reached by taxi from Boa Viagem (R$200 or so) in combination with a visit to Oficina Cerâmica Francisco Brennand .
An economic route to the museum is to catch a CDU/Caxangá bus (R$2.45) from Boa Viagem to the end of its route on Rua Acadêmico Hélio Ramos, then a taxi round-trip from the bus stop to both here and Oficina Cerâmica Francisco Brennand (around 10km in total) for around R$80 to R$100.
