Geological Chronicle
Lagalla is the remnant of a lunar impact crater in the Moon's southern hemisphere, spanning 88.78 kilometers in diameter. The feature is named for the Italian philosopher Giulio Cesare Lagalla and lies within the Wilhelm quadrangle.
The crater's perimeter is marked by adjoining formations. Wilhelm partly overlies its northeastern rim, Montanari is attached to the southeast, and the irregular satellite crater Lagalla F is attached to the western rim.
Small craters overlie sections along most sides of the heavily eroded rim, leaving the wall nearly nonexistent to the south. The most intact portion lies along the northwest, encircling an uneven and relatively featureless floor.
