Bosa is a small town on the left bank of
the river Temo, in a pleasant valley
contrasting with the stern encircling chain
of mountains looming in the background,
to the North. Its plan is fairly regular: part
of the old town is on the slope of a hill
dominated by the Castello di Serravalle,
while the modern district stretches with
its avenues and squares towards the sea.
The ancient town of Bosa is vaguely
mentioned by Ptolemy, in the itineraries.
It is of pre-Carthaginian origin and long
before that, in the countryside of Bosa and
in the valley of the river Temo, there were
Nuragic buildings and prehistoric tombs.
The former, though, were destroyed as
centuries and civilizations went by. Where
the Carthaginian town was situated we do
not Know. In the Roman period the town, a
municipium with   prior  magistrates,  
certainly was around the place where the
church of S. Pietro is now. It was
connected with Tharros and Cornus on one
side, with Turris on the other, by road. In
the Middle Ages the Malaspina family had
the castle of Serravalle built: at that time
Bosa was important as one of the two (the
other one was Oristano) landing-places,
for ships from Spain.
Bosa is famous for its lace, the making of
which used to absorb the talent of most of
the female population. Other riches of the
area are figs, artichokes and Malvasia
wine. It is worth visiting the small church
of S. Antonio, dating from the XVth
century, a local adaptation of the
Aragonese-Gothic style.
We cross the bridge on the river Temo
(lovely view over the river) and, on the
other bank, we can admire   the   
Cathedral   with   its small picturesque
domes and the sturdy bell-tower. From
there starts Corso Vittorio Emanuele the
main street of Bosa, lined with high
houses with lovely balconies. Going down
the Corso, we get to the small church of
the Rosario, with the big clock and the
characteristic small belfry. We go past
Piazza Umberto I with its marble fountain
and reach the wide tree-lined square with
flower-beds where the War Memorial is. It
is well worth going to see the Castello di
Serravalle, built in 1112 by the Malaspina
family ac¬cording to some, in 1121
ac¬cording to others: the remains consist
of the boundary wall and towers.
A lovely walk (about 2 km) is the one to S.
Pietro Extramuros (ait. 14 m.) along the
secondary road ("carrozzabile") which
goes from the church of S. Antonio up the
bank of the river Temo (see above). This
church is in a picturesque corner by the
river and it bears in its present structure
the mark of a long building process which
took place between the year 1073 and the
first half of the Xlllth century, in three
distinct phases. Another excursion is the
one to the beach of Bosa Marina.
