A Carlist group in the northern Spanish region of Asturias has caused controversy by seemingly calling for beaches to be segregated by sex.
"Catholics, preserve your decency in summer, too: Don't go to mixed beaches!" reads the poster, uploaded by the Traditionalist Group Pedro Menéndez de Avilés to its Facebook page.

The poster was accompanied by a list of recommendations that good Catholics should follow during the holiday season in Spain.
The accompanying text, entitled Summer Holiday, includes extracts from the Norms of Christian Decency, a set of rules published by Spanish bishops in 1958.
The text warns people to "avoid mixed bathing" because "it almost always entails close proximity to sin and scandal".
"The scenes that you see on mixed beaches are often close to sin," a spokesman for the Carlist group told The Local.
Carlism was a traditionalist, political movement in Spain linked closely to the Church. It was a significant political force throughout the 19th century and up until the death of dictator Francisco Franco in 1975; Franco counted several Carlists among his ministers.
The group also includes advice on what people should wear to the beach in order to preserve their modesty.
Men should wear "a simple bathing suit" while women are advised that their swimsuit should "cover their body" and include "a little skirt for when out of the water".
If bathers can absolutely not avoid going to a mixed beach or pool, the group advises that swimwear should be "more modest" and be used "only when in the water". As soon as bathers leave the water they should "cover themselves with a dressing gown (bath robe)".
The Carlist group which fights for "Catholic resistance" against the "current modernist Church" encourages Catholics to search out beaches that are segregated by sex because "some remain".
"If there are no segregated beaches close by, we think the best option is to not go to the beach," said the group.
The group also has some advice for tourists; Spain was recently rated the world's most tourist-friendly country, but the group urges tourists to "set an example to their compatriots and to local Spaniards".
"Of course we oppose these drunk tourists who are infecting our beaches," the group told The Local.
"We believe that this kind of tourism poses a real danger that is much worse than other "immigration" that is coming from the south," the group added.
