The Tailors' Tower (Baba Novac Street / Stefan cel Mare Square) is part of the second fortified precinct of the walls system and of the fortifications of the city, built in the first half of 15th century and continued until the 17th century. It was built on the South-Eastern corner of the city defence wall, after 1405, following the privileges keyed by King Sigismund of Luxemburg. The first confirmed documents date 1457, from the time of King Matia Corvin.
The administration of the Tower was entrusted to the most powerful guilds of the town – the tailors' guild. Over time, the Tower was devastated several times (1551-1553, 1601, 1627, and 1707). The actual shape is given by the last big reconstruction from 1709-1711, made by the Austrians, out of over 150 stone wagons. The Tower has renewed again in 1956-1957 when they attempted the opening of a history museum of the city of Cluj, a project forbidden by the communist authorities in 1959. http://www.visitclujnapoca.ro/en/atractii-turistice/monumente-si-complexe-arhitectonice/page/4/the-tailors-tower.html
The Vivarium was built between 1998 and 2001 out of the Babes-Bolyai University and the Biology and Geology Faculty funds. It contains approximately 57 animal species. When it opened in 2001, it only sheltered a collection of reptiles and amphibians. Currently, alongside the reptile collection, the Vivarium also hosts 10 fish species, 9 micro mammal species and 6 bird species, out of which we can mention the Puff Adder, the Rainbow Boa, the leopard gecko, the Nile monitor, the chinchilla, the Dobrogea turtle, the salamander etc. http://www.visitclujnapoca.ro/en/atractii-turistice/muzee/page/3/the-vivarium.html
The two cultural institutions were founded in 18th September 1919, as an expression of spiritual rebirth after the Great Union in 1918. The building which houses the „Lucian Blaga” National Theatre and the Romanian Opera was built between 1904 and 1906, as a seat for the Hungarian National Theatre, by the famous Viennese firm „ Fellner und Helmer”, combining stylistic elements of new-baroque and Secession. The hall has 928 setas and it is built in New-Baroque style. For decorating the lobby were used stylistic modulations inspired by Secession. The National Theatre and the Romanian Opera have been functioning there since 1919. The opening show of the National Theatre of Cluj took place on 1st and 2nd December 1919, with the plays „Se face ziua” by Zaharia Barsan and „Ovidiu” by Vasile Alecsandri. The „Eupharion” Studio of the National Theatre is specially designed for the young artists and their creative experiments. The Romanian National Opera from Cluj Napoca is the first lyrical dramatic state institution from Romania. The inaugural show took place on 25 May 1820, with the play “Aida” by G.Verdi. More than 200 titles of operas, operettas and ballets from the world repertoire have been put on scene at the Romanian Opera so far. http://www.visitclujnapoca.ro/en/atractii-turistice/best-of-cluj-napoca/the-lucian-blaga-national-theatre-and-romanian-opera.html
