The monumental wood carved retable, incorporating free-standing figures and relief-sculpted panels, was spread mostly by the work of Flemish artists who had settled in Portugal. 17th century wood carving portrayed naturalistic and geometric themes which filled the entire space, making the pieces more decorative. The author of this piece, evocative of Our Lady of the Immaculate Conception, is the sculptor Manuel da Rocha whose artistic training is unknown, although it shows some affinity with the work of the Castilian wood carvers, widely divulged in 17th century Portugal.
The central figure in this retable is an image of Our Lady of the Immaculate Conception, patron saint of the kingdom following the Restoration of Independence in 1640.
