To all our dear incoming exchange students, welcome to the official 2nd Home city tour of Porto. I am Kika! And I am Joana! And were about to take you on a historical trip through one of the oldest cities in the world (yes, you heard it. Porto dates back to the Roman period, 8th century BC to be precise). Brace yourselves for an adventure. Besides, you are in the undefeated city, ‘A Cidade Invicta’. Are you ready?
