I was really lucky I could enter, as the site was already closed when I arrived on a Saturday at 12:30. The friendly keeper let me in, so I could have a look at what is unfortunately a very underwhelming WHS. The area itself is tiny. You can see it in about 5 minutes. The only decent building is reconstructed. From the rest, only a few walls or even less is left. It has very limited opening times. Mon-Fri 9-4. Sat 9-12, Sun closed. Fun fact is that it’s basically signposted from the airport on the other end of the island.
