I have finally come across the answer and it is a bit out of the ordinary!
Do you remember this 14th Century Door, the Door of Chains.
In the past there were bollards outside in front of the church ( you can see one of the remaining ones in the front righthand corner of the photo above) with chains attached which marked a small area in front of the church door. Now then, before this church was granted cathedral status in the 16th century this church belonged to the diocese of Cartagena (Murcia).
It is well known that in the past there was a religious custom where fugitives could claim sanctuary within-side a church and no authority could come in and harm, arrest or remove the fugitive for punishment. However, this church went a little further than that and any wrongdoer who jumped the chains into that small area in front of the church door could claim sanctuary there too even though they weren't actually inside the church itself and so escape the civil jurisdiction of the authorities in Orihuela (Alicante) at that time.
There you go, hence the name "Door of Chains".😀🚪
A light at the end of the tunnel
Two weeks ago we went up to the Agost Mountains and enjoyed the sun, the scenery and the exercise.
A nice strenuous walk along the Maigmó Greenway trail again. This time we went further along and we still didn't get to the end of the trail.
