Il-Maqluba (meaning overturned or upside-down in Maltese) is a sinkhole with a surface area of around 4,765 square metres (51,290 sq ft) situated in the village of Qrendi in Malta.

[1][3] A variant of this legend speaks of a nun as saved while praying in the small San Mattew Crypt during the occurrence.

One particular species that merits special mention is the sandarac gum tree (siġra tal-għargħar) which naturally occurs in North Africa, Southern Spain, and in Malta growing only at Maqluba and Imġiebagħ and in the Mellieha area Under these trees other plants thrive such as the large-leafed nettle (ħurrieq) and the cleavers (ħarxajja komuni).

Thus one notices the Maltese salt tree (xebb), the ivy (liedna) and the caper (kappara), but also the prickly pear (bajtra tax-xewk) and the omnipresent Bermuda buttercup (ħaxixa Ingliża) along with many other plants.

The sinkhole is also a nesting site for the national bird of Malta, the blue rock thrush (Monticola solitarius).
