Come and discover Lisbon with me, so many times nicknamed by poets as the "white city" or the "city of light". Stop by the Belém Tower, an ornate and distinctively shaped fortress dating from 1515, then walk to the Monument to the Discoveries, which celebrates Portugal's golden age. Also honoured with UNESCO World Heritage status is the magnificent - and my favourite - Monastery of Saint Jerome. No trip to Belém would be complete without sampling the delectable Pastéis de Belém - warm custard tarts with a light, crunchy casing, served here since 1837.
