Church of Santa Maria do Olival, Gothic church from 12th century in Tomar, Portugal.

The Church of Santa Maria do Olival has a main facade of pale yellow and grey stone blocks, with a large rose window of twelve trilobed leaves above a gabled portal of four pointed archivolts on columns. A small carved medallion sits in the gable, and a red double door opens beneath layered moldings. Inside, three naves of five bays have pointed arches on faceted cruciform pillars without capitals, under a wooden roof.

Founded in the late 12th century by Templar Master Gualdim Pais, this church initially served as the main burial ground for the Templars. It later remained an important burial site when the Order of Christ took over the region.

The church is dedicated to Nossa Senhora da Assunção, and its name recalls the olive grove that once stood here. Look for the pentagram carved in the tracery of the small rose window in the nave's eastern wall. In the left nave, a slab bears the arms of two families and the faded letters "T.DA.CUNHA", likely marking a relative of commander Tristão da Cunha.

The church stands on the left bank of the Nabão, with its medieval bell tower separate from the facade in the churchyard. The main entrance faces the rose window and gabled portal; the 12th-century round-arched north door is also visible. The interior has three naves of different heights, the central one tallest, so the main chapel is reached directly through the triumphal arch.

The tomb slab of Gualdim Pais from 1195 remains inside the church, bearing one of Portugal's oldest Gothic inscriptions. This carved stone tells much about early Gothic writing styles in the country.
