Yes, the monastery has an on-site shop located right next to the ticket desk (www.mosteirodetibaes.gov.pt). It sells a variety of souvenirs and cultural items: books about the abbey’s history, replicas of Baroque artwork, local artisanal crafts and jewelry, postcards, and stationery. Importantly, it also carries the abbey’s own food products (like honey, liqueurs and olive oil with the monastery’s label) and exhibits pieces of local craftsmanship. You can find a keepsake or educational book there if you wish. The shop accepts cash or card (www.mosteirodetibaes.gov.pt), and the same counters are used for both tickets and purchases, so you can pay for souvenirs at the entrance/exit. If you need more specialized pilgrim items, ask the reception, as they may have additional religious goods in stock that aren’t on the open shelves.
