The former royal palace of King Roger II in the 1100s, Palazzo dei Normanni is one of the most famous sights in Palermo. Dating back to the 9th century, the palace owes its current appearance to the embellishments realised by the Normans: covered in dazzling Byzantine mosaics, the Arab-Norman architecture is a symbol of the political and cultural union operated by the Normans. Be sure to check out the stunning Palatine Chapel.

Built in the early 14th century in Norman Gothic style, Palazzo Chiaramonte Steri, one of the symbols of Palermo, bears witness to a multifaceted history as both a tribunal and prison under the Inquisition from 1600 to 1782. Today, it serves as the headquarters of the University of Palermo, offering visitors a glimpse into history through its marvellous lecture halls adorned with intricate 14th-century wooden ceilings. The Inquisition Museum within its walls unveils the poignant narratives of prisoners through haunting graffiti and artworks, etching their stories onto the very cells that once confined them.

Founded in 1781, the Orto Botanico di Palermo is considered to be a prestigious open-air botanical museum that has enabled in-depth studies on fascinating plants for about 200 years. Walk down the shaded pathways lined with subtropical plants, fig trees, Mediterranean herb gardens, local cacti, and hibiscus but don't forget to also check out the beautiful historical buildings where this restful paradise is set in.

One of the finest examples of Medieval architecture in Palermo, the church of Saint John of the Hermits (Chiesa di San Giovanni degli Eremiti) is famous for its red domes and architectural design that was greatly influenced by the Arabs during the 12th century. This was originally a mosque that was later converted into a Christian church dedicated to Sicily's hermit monks. Walk along the pretty garden of regional plants and the ruins of the cloister.
