Adjust your eyes. This is the crazy cobble pattern of Rossio Square in Lisbon – a major coffee house meeting place for many decades. It lies near the wide Tagus River at the foot of this leafy avenue – a relic of the centuries-long colonial era, when sailing ships thronged the river estuary bringing wealth from Brazil, Angola, Mozambique and as far as Macau and Timor. Even today, Portuguese is the official language of ten countries, particularly Brazil. An Angolan artist has been commissioned, on a popular vote, to construct a slavery memorial in 2020, alongside a museum addressing the effects of those years – laying out the the truth and helping the healing!
