Imposing parish church, designed by Ludwig Becker, built between 1900 and 1904 in the neo-gothic style in Heppenheim, Germany, also known as the Cathedral of the Bergstraße.

The St. Laurentius Church is in the center of the old town of Weinheim, Germany. It was built between 1911 and 1913 according to the plans of Ludwig Maier.

The awe-inspiring underground concert hall in the Baradla Cave, part of the Aggtelek National Park, Hungary. In 1995, the national park and the cave system were declared part of the World Heritage by UNESCO.

Although designated as a concert hall, the lush reverberation resembles a cathedral.


St. Michael's Church - Cluj-Napoca (4.4 s)

The vast St. Michael’s Church is one of the finest examples of Gothic Roman Catholic architecture in Romania, built in the 14th century. It is the second largest church in Transylvania.

Inside, you can find an aisle-less church, which is 32 meters long (without the altar) and 14 meters wide. The tower of the church is a very impressive sight and the church is still a very characteristic mark of the district.

Since then, it has also been used as a philosophical-theological college and as a conference center.


Ev. Johanneskirche - Darmstadt (3.6 s)

The Johanneskirche is a neo-gothic church in Darmstadt, Germany, built at the end of the 19th century. After being almost completely destroyed in the Second World War, the church was rebuilt in 1952. The church is relatively large compared to its reverberation allowing a spacious but clear sound.


The Notre Dame of Kaposvár - Kaposvár (3.6 s)

The Notre Dame of Kaposvár, also called The Our Lady of the Assumption Cathedral is one of the largest Christian churches in the region, located in the historic center of Kaposvár. The neo-romanesque cathedral was designed by Ottó Tandor. Its construction began in 1885 and was completed in 1886.


Giants' Hall - Jósvafő (3.5 s)

The largest hall of the Baradla Cave system, part of the Aggtelek National Park, Hungary. In 1995, the national park and the cave system were declared part of the World Heritage by UNESCO. A truly breathtaking place with minimum obstructions and monumental acoustics.


St. Peter’s Church - Ébersviller (3.4 s)

The relatively small but tall neo-gothic church is situated in Ébersviller, France, and was built in 1879. The construction wasn’t without difficulties, and its success was highly dependent of parish priest Dominique Durant’s dedication. The acoustic qualities of the church make it a unique location for concerts.


Melbourne Town Hall - Melbourne (3.1 s)

Since its completion in 1870, the magnificent, historic building designed by Joseph Reed, has served as the center of multiple cultural and civic events such as concerts, theatrical plays, exhibitions and many more in Melbourne, Australia.


Chautauqua Institution Amphitheater - Chautauqua (2.9 s)

The 4500-seat Amphitheater was completed in 2017, replacing a historic old structure in Chautauqua, NY, USA. It serves a wide range of needs of the community, including arts, culture, worship, and many more. Although the space is a semi-open concert hall without side walls, the acoustic quality of the space is exceptional, and its unique outdoor pipe organ sits in better acoustic conditions than in many concert halls.


The Basilica of the Benedictine - Pannonhalma (2.6 s)

The Basilica is part of the Benedictine Pannonhalma Archabbey, one of the oldest historical monuments in Hungary and the second largest territorial abbey in the world. The construction of the current building, a crowning achievement of the early gothic style, started in the early 13th century, using the walls of the former church. A magnificent building with a lot of history and a spellbinding atmosphere. Acoustical measurements took place before the recent reconstruction.


Royal Concertgebouw - Amsterdam (2.5 s)

The world-famous concert hall in Amsterdam, Netherlands. Designed by Adolf Leonard van Gendt and built between 1883 and 1888, it is one of the world’s most prestigious concert halls with exceptional acoustic qualities. The hall is 44 meters long, 28 meters wide, 17 meters high and seats more than 1900 people.


Urakami Cathedral - Nagasaki (2.3 s)

The original cathedral, the largest in East-Asia, was built between 1895 and 1914, but during WWII it was completely destroyed when the atomic bomb hit Nagasaki on the 9th of August, 1945. The reconstruction of the building was completed in 1959 and then remodeled with brick tiles to its current form resembling the original neo-roman style in 1980. The cathedral has a central role not just in the city, but also in the region.


The Scots’ Church - Melbourne (2.3 s)

The present neo-gothic church was designed by Joseph Reed and was opened in 1874, in Melbourne, Australia. The exterior of the church wasn’t altered much in the following century while the interior was reorganized in 1930, when the splendidly carved stone pulpit and reredos were replaced. The interior reflects simplicity and restraint in design and decoration. The acoustics of the church provides exceptional clarity.


Berliner Philharmonie - Berlin (2.2 s)

The highly regarded concert hall with an asymmetrical, tent-like shape and innovative architecture, located in Berlin, Germany. Built between 1960 and 1963 according to the design of architect Hans Scharoun, the main hall is in the shape of a pentagon. Unconventionally, the stage is at the center of the hall, surrounded by seats on all sides with irregularly increasing row heights. The hall has exceptional acoustic qualities and sonic clarity.

Bartók National Concert Hall

Béla Bartók National Concert Hall - Budapest (2.2 s)

The Palace of Arts or Müpa Budapest is a cultural institution located in the capital of Hungary. Officially opened in 2005, its central space is the internationally acclaimed Béla Bartók National Concert Hall.
