The major stops were in churches with affiliated monestaries and convents:
Convent of Espinheiro, Evora, now a hotel, where the conference was held
Mosteiro dos Jeronimos with Santa Maria de Belem, Lisbon
Mosteiro da Batalha
Mosteiro de Santa Maria, Alcobaca
Convento de Christo, Tomar
We also visited nifty hill towns, including Estremoz, Sintra, Obidos, and Marvao, the Roman ruins at Conimbriga (the best in Iberia, but not to be compared to Tunisia), and Elvas, sister city to Graceland. The hill towns all have well-preserved medieval castles, which are so common in Portugal as to merit little comment.
