  • If you teach geology, this is an excellent place to show an old and well preserved volcanic chimney and the basalt forms, namely prismatic columns, generally pentagonal or hexagonal (with 5 or 6 faces), formed by the rock contraction due to fast cooling. This old conduct, about 72 million years old, is part of the Lisbon Volcanic Complex. From this high point, you can see several other conducts of old volcanic chimneys.
