Obidos is the finest example of a Portuguese walled town, and is one of the best tourist destinations of the Lisbon region.
Historically, Obidos was presented to the Queen of Portugal on her wedding day, a tradition that began with Queen Urraca in 1214 and continued until the 19th century. This royal patronage has left an enduring legacy of pride within the town, and today it is one of the most characterful towns of central Portugal.
For visitors, Obidos is a charming and popular town to explore; there are narrow-cobbled streets, traditional painted houses, and an imposing medieval castle. Obidos is a small town, but there is no better example of a traditional Portuguese town.
Obidos has charming artisan bakeries. They make a local cherry licor called Ginjinha which they sell and serve with chocolate cups and their baked goods are the best in the area. Truly a delight for those looking for charm and to satisfy a sweet tooth.
There are ambulant markets in the main street that sell clothing and other hand made goods. I would certainly recommend walking through those streets. Do expect to find lots of tourists as this is one of the most beautiful towns in Portugal.
