The lowest part of the sundial on the southern
 wall (6) is about level with the top of the entrance door (2). The style is gone,
 but the red paint of the dial did survive. The design is plain without frills
 (or maybe that ornaments are weathered away) but drawn with precision.
 Notice the marks for the hours, half hours and even the quarters.
Because the wall isn't oriented exactly to the south, but turned to the west,
 the sun can't cast a shadow during the first hours of the day. That's why
 the maker of this sundial didn't bother to paint any mark before ten.
 Because of the wall's inclination the scale is also asymmetrical. The distances between
 the early hours (10-13) are smaller than between the later hours (14-18).
Not far from Jánovas in the direction of Boltaña lies Ascaso
 where you'll find two beautiful sundials.

Normally the shadow at noon (12h local suntime) lies vertically below the
 insertion point of the style. Here a 13 was written which means that
 the legal time is shown (noon at 15° east). The 13-mark is slightly off the vertical.
 That is probably meant to adjust for the position a bit to
 the west of the meridian (of Greenwich). It makes that 1 pm is reached a trifle earlier
 than local noon, thus before the shadow falls straight down.
The second sundial (7) is facing east and
 therefore complements the first. It will catch the early morning light, but
 lie in the shadow from noon. The scale stops at 12. So there is an overlap between
 the two dials.
