San Martín el Real

Seventeenth century, probably, so not Romanesque, although elements of it - including the corbels - may be from that epoch. But it´s the highest and tallest building in Torazo and it has the most intimidating staircase. 
For a splash of colour - a small one - there´s an extra. 
The EXIF is incorrect: the lens is a Samyang 12mm f2, the photo I think was taken at f8.
