San Marcos Castle is a 12th-century fortress, commissioned by Alfonso X 'The Wise' upon the remains of a Moorish mosque on the banks of Guadalete River. Despite being so old (800 years), the castle is preserved in perfect conditions of use. Cultural events, conferences, lunches or dinners can be held both inside or outside in the garden, for up to 300 people.
The inside of the old mosque is an ideal place for events and closing dinners for conferences and conventions, because of its historic atmosphere. During the summer, the area around the fortress is an incomparable venue for celebrating open-air events.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
