The former museum in Luxembourg City's "Verlorenkost" neighbourhood allowed visitors to dive into the eventful history of the country's police.

The museum has been closed to the general public since December 2016. Even though officials hope that the museum may eventually reopen its doors, its future looks uncertain for the time being - "SORRY, NO GUIDED TOURS," the museum's website currently reads.

The buildings are run-down and, in the past, officials have already considered tearing them down altogether in order to create space for new apartments.

About this series

In this popular series, RTL photographer Domingos Oliveira takes you to hidden places, lesser known locations and buildings with an interesting story.

1) The first installment captured the last moment of the agricultural centre in Mersch.

2) We then visited Zenningen Zoo, which was closed in the early 80s. 

3) Our third trip took us to Hesperange's eery swimming pool which now looks like the setting for an apocalyptic film.

4) The fourth photo series targeted the veritable ghost town "Cité Syrdall."

5) We also visited the iconic cinema Ariston in Esch, which opened in 1962 and closed in 2016. The cinema's history is an eventful one - from erotic films to youth theatre.

6) In the sixth installment, we took a trip down memory lane and revisited pictures of Luxembourg City's former "centre Aldringen," an underground parking lot and cultural hub that gave way to Centre Hamilius.
