Gilded woodcarving in Portugal is, along with tile, one of the country's most original and rich artistic expressions. It is usually used in the interior decoration of churches and cathedrals and of noble halls in palaces and large public buildings. An impressive collection of altarpieces are found in Portuguese churches. Originating in the Gothic era, Portuguese gilded woodcarving assumed a nationalist character during the 17th century and reached its height in the reign of King D. João V. In the 19th century it lost its originality and began to disappear with the end of the revival era.
