Kempinski Palace Portorož, until 2008 known as Palace Hotel (Slovenian: hotel Palace), is a five-star deluxe hotel in Portorož, a settlement on the Adriatic coast in southwestern Slovenia. It is the only deluxe hotel in Slovenia.
The central part of the hotel is the Crystal Hall (Slovenian: Kristalna dvorana).
The hotel began to be built in 1908 upon the plans of the Austrian architect Johann Eustacchio and opened on 20 August 1910 at the time of Austro-Hungarian Empire. At that time, it was a tourist attraction of the highest quality. Portorož was, together with Grado and Opatija, categorized as one of the most important coast resorts and spas on the Austrian Riviera. The construction of the hotel was completed in 1912. At the end of 1983, it was proclaimed a cultural monument, and a park in front of hotel was called a monument of designed nature.
The hotel was closed in autumn 1990. In the 2000s, the Slovenian owner, coastal company Istrabenz Hoteli Portorož, signed a contract with a German hotel chain Kempinski to run and manage this hotel for at least 20 years. When they renovated the hotel, the exterior was kept for historical reasons and almost everything else was demolished; however most of the interior was rebuilt in the classical style. The renovation was planned by Slovenian architects API ARHITEKTI and cost about 70 million euros. In addition, a modern hotel building was built next to the original hotel. The hotel was reopened on 18 October 2008.
