If King Fernando II of Aragon were reincarnated in the 21st century, he’d probably still recognise his modest birthplace in Sos del Rey Católico. Take away the motor vehicles and summer tourist crowds, and outwardly not a huge amount has changed in this small, tightly packed hilltop village since 1452 when the future husband of Isabel of Castile and king of a united Spain was born in the Sada palace. Legend has it that Fernando's mother travelled 14km on horseback from Sangüesa in Navarra while already in labour, purely to ensure her son was born Aragonese.
Royalty aside, Sos is a fine place to soak up the feel of an old Aragonese village. When you’ve finished having historical hallucinations in its labyrinthine streets, you can investigate the network of mossy walking paths that dissolve into the surrounding countryside.
