One of the seven wonders of the ancient world. The site is interesting if you enjoy ancient history/archaeology. The exhibits mainly consist of carved panels and friezes. The best sculptural reliefs ended up in museums in other countries. Plenty of information in English and Turkish about how and when it was built and the excavated site is worth seeing. Not for children, they would be bored within 5 minutes. A few benches in shade provide relief from the sun. Entrance fee was 10 Turkish Lira pp in May 2018.

Wonderful place to visit seeing one of the 7 wonders of the ancient world 10 lira to get in well worth a visit

One of the 7 wonders of the ancient world. Unfortunately it was pillaged for it's stone but the site today is still beautiful being surrounded by tall shady trees and rose bushes. It's very informative lots of information on the site and you can climb over pretty much all of it to your heart's desire. A must if you want a quiet break in bodrum or if you are a history buff.

The Masonic House of the Temple of the Scottish Rite, Washington, DC, John Russell Pope, architect, 1911–15, another scholarly version. The Mausoleum at Halicarnassus or Tomb of Mausolus[a] (Ancient Greek Turkish: Halikarnas Mozolesi) was a tomb built between 353 and 350 BC at Halicarnassus (present Bodrum, Turkey) for Mausolus, a satrap in the Persian Empire, and his sister-wife Artemisia II of Caria. The structure was designed by the Greek architects Satyros and Pythius of Priene. The Mausoleum was approximately 45 m (148 ft) in height, and the four sides were adorned with sculptural reliefs, each created by one of four Greek sculptors—Leochares, Bryaxis, Scopas of Paros and Timotheus.[3] The finished structure of the mausoleum was considered to be such an aesthetic triumph that Antipater of Sidon identified it as one of his Seven Wonders of the Ancient World. It was destroyed by successive earthquakes from the 12th to the 15th century, the last surviving of the six destroyed wonders. The word mausoleum has now come to be used generically for an above-ground tomb.

It's a worldwonder so yeah why not visit, but nearly nothing left. At the end you see nearly nothing but you can say you visited a worldwonder. Really cheap entrance fee.
