The Roman Geira, a roman path built in the year 75ad connected Bracara Augusta to Asturica Augusta in Spain.The Roman mile (mille passus, lit. "thousand-pace"; abbr. m.p.; also mille passuum[n 2] and mille) consisted of a thousand paces of two steps each. The ancient Romans, marching their armies through uncharted territory, would often push a carved stick in the ground after each 1000 paces. Well fed and harshly driven Roman legionaries in good weather thus created longer miles. (Wikipedia)
The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida, Spain). It was constructed in the years 15 to 16 bc The theater has undergone several renovations, such as at the end of the 1st century or early 2nd century, possibly during the reign of Emperor Trajan, when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), introducing new decorative-architectural elements and a walkway around the monument. After the abandonment in Late Antiquity, it was covered with earth, only the upper tiers of seats (summa cavea) remaining visible. The popular imagination called it "The Seven Chairs", where, according to tradition, several Moorish kings sat to decide the fate of the city.
An amphitheater is an open-air venue used for entertainment and performances. The term derives from the ancient Greek ἀμφιθέατρον (amphitheatron), from ἀμφί (amphi), meaning "on both sides" or "around" and (théātron), meaning "place for viewing".
