The Hill O Many Stanes is an area with about 200 upright stones, none more than a metre high. The rows are not parallel, however, and they create a fan-shaped pattern. This arrangement is believed to be a relic of Bronze Age times.
In Megalithic Lunar Observatories (Oxford University Press, 1971) Alexander Thom presented evidence that the stone rows were in effect a Bronze Age lunar observatory, tracking lunar movements over a cycle of 18.6 years. However, more than twenty similar stone rows are now known in Caithness and Sutherland and none of the others has been linked with astronomical observations.
In Britain stone rows of this kind are unknown outside Caithness and Sutherland, but similar rows of much taller stones are found in Brittany, France.
References:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
