The Čachtice castle ruins stands on a hill featuring rare plants, and has been declared a national nature reserve for this reason. The castle was a residence and later the prison of the Countess Elizabeth Báthory, who is alleged to have been the world's most prolific female serial killer.
Čachtice was built in the mid-13th century by Kazimir from the Hont-Pázmány gens as a sentry on the road to Moravia. Later, it belonged to Máté Csák, the Stibor family, and then to the famous Bloody Lady Elizabeth Báthory. Čachtice, its surrounding lands and villages, was a wedding gift from the Nádasdy family upon Elizabeth's marriage to Ferenc Nádasdy in 1575.
Originally, Čachtice was a Romanesque castle with an interesting horseshoe shaped residence tower. It was turned into a Gothic castle later and its size was increased in the 15th and 16th centuries. A Renaissance renovation followed in the 17th century. Finally, in 1708 the castle was captured and plundered by the rebels of Ferenc II Rákoci (Francis II Rákóczi). It has been in decay since.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
