Rome's Tempio di Adriano, or as it is known in English, the Temple of Hadrian (Hadrianeum), is one of the city's lesser-known attractions, it's a similar building to the Pantheon, which is located nearby but also far less busy. It dates back to the Roman era, with the building dedicated to Emperor Hadrian after previously being known as Basilica of Neptune before Hadrian's adopted son and successor, Antoninus Pius, dedicated to him.
It is located in the Piazza di Pietra.
Nowadays, it is home to the Rome Chamber of Commerce. There is free entry for tourists to sit down and watch a quick video and explore the rooms of the building, there also appear to be some ticketed events too.
The craft of the pillars and columns both on the inside and outside of the building is truly impressive, and the Roman structure which stands to this day adds further beauty to the eternal city.
The employees seemed happy to let tourists sit down inside without being too pushy or bothersome, and the atmosphere inside was nice, being able to sit and watch the free video.
The layout could have been easier to follow when inside, but this wasn't too much of an issue as most tourists will only be using the main dome anyway.
4* - Certainly not the most essential and must-do activity while in Rome, but certainly worth spending some time here, especially on a longer stay in the city, and the central location right by the Pantheon means you won't have to detour to visit. read more
