sundials in Quito

[Willy Leenders]

I visited the website http://www.sundials.co.uk/~ecuador.htm

Quito lies about 10 miles south of the Equator, so that gnomons parallel
to the earths axis are horizontal.

But at the sundial outside the main entrance of the Universidad Central
de Quito (picture 2) the gnomon is not horizontal.

Hour lines on a vertical sundial at the Equator forms angles of 15
degrees between them.

That is not so on the sundial near the church of Guapolo (picture 1)

Who can explain this?

Regards
