Dating all the way back to 1681 and standing at the outer reaches of Lisbon, on its far north-western edge, the Grand Palace of the Marquises of Fronteira is one of the more off-the-beaten-track remnants of the city’s most former glory. Despite its remote location it is still easy to get to and offers a glimpse of the majestic architecture that came to the fore in the 1600s and 1700s in Portugal. The home was once that of the Marquis of Fronteira, who received his land and wealth after staying loyal to the Portuguese royal name during the Restoration War of the mid-17th century.
