The Saluting Battery is Valletta's ancient ceremonial platform from where gun salutes are still fired regularly. Equally, the passage of time is marked twice daily from her with gun fire at noon (12:00) and sunset (16:00).
The battery itself is located at one of the capital's highest vantage points from where splendid vistas of the Grand Harbour and its surrounding towns can be enjoyed. Its origins go back to the time when Valletta was built by the Order of St. John in 1566. It remained in constant use, under the Knights, the French and the British in both its defensive and ceremonial roles for the next 400 years. This historic monument has recently been restored to all of its original functions as it stood in the late 19th century, complete with working cannon, artillery stores, gun powder magazine, historic ordnance collection and small museum.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
