Ggantija. Interior, post-and-lintel niches.
The walls of Ggantija (upper part of photo) are made of rough coralline limestone, in contrast to the interior architectural elements (lower part of photo) which are made of Globigerina limestone. The soft Globigerina limestone is more easily worked and smoothed. This makes it suitable for interior finishing, such as the trilithic niches shown here.
