Lanzada is an archaeological site is composed of a castro (hillfort settlement), a necropolis, a medieval fortification and a chapel. A bronze socketed axe with two loops was found in the vicinity of the town of A Lanzada and is now housed in the National Archaeological Museum. Three more axes were uncovered in another part of the site, two of which belonged to the Marquis of Riestra and one that he gifted to an English subject. In the summer of 1969, a bronze Irish-style sickle was found among the remains of a landslide in the Norte del Castro area near the chapel.
Excavations revealed the existence of a castro settlement and a large late Roman necropolis with cremation and inhumation tombs. Bone and bronze pins, coins, shoe nails, and tegulae or flagstone graves were also recovered. The settlement and the necropolis are on both sides of the road. In 1969 and 1972 a stratigraphic analysis confirmed the existence of the settlement and its occupation from the late Bronze Era to the last stages of the Romanisation process, which makes it very significant.
Lastly, there is a Roman stela on the south side of a path known as A Ponte, which connects the mainland to the isle where the chapel is located. Fragments of castro pottery were found on the isle.

The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
