A parish was founded late, in 1880, for the small Catholic community of the town, mainly inhabited by Calvinists. The Catholic population only grew in the second half of the 19th century. It previously belonged to the parish of Mezőbikács. Its church was built after 1875.

The church was built between 1750 and 1755 with donations from wealthy farmers in neoclassical style. It was once surrounded by walls reinforced with bastions. The church was damaged by fire in 1847 and rebuilt between 1853 and 1854. Between 1902 and 1918, the Reformed Diocese of Nagyszalonta had as its trustee Count Tisza István, whose 150th anniversary was commemorated by a plaque on the church wall. Tisza István was the prime minister of Hungary. The tower clock marks the passing of time with the Kossuth song.

The church was built in 1903 as the first Hungarian Baptist house of prayer. In 1871, the first new-age Baptist congregation began to develop in Nagyszalonta, when Novák Antal, a Bible seller, found a Bible reading group of 7-8 people (led by Lajos János, a gunsmith).

The town hall was built between 1906 and 1907 in the Art Nouveau style. It was designed by Székely László, whose father was a master mason from Szalonta.

The town council decided to establish a secondary school in 1903. It was established as the first state secondary school in Bihar Count in 1907, and the school building was completed by 1909, based on the plans of Székely László. With the Romanian occupation in 1919, it became a mixed-language school. In 1941, after the Second Vienna Award returned the town to Hungary, the school took the name of the poet Arany János. After the renewed Romanian occupation, it changed its name several times, and in 2007 it took the name of Arany János again. From the 2012-2013 school year, only Romanian classes were launched in the school. In 2013, the town council renamed the school to Teodor Neș. There is a new Hungarian school in the town bearing the name of Arany János.

From 1711 we have written documents about the Schola Reformata Nagyszalontaiensis, where the poet Arany János studied and taught. In 1847 the building, now called the Great School, was built, which housed both the lower and upper grammar schools.

In 1906, the Civil School for Girls was established, with four elementary classes, which was later expanded to include a commercial course. The following year, the boys' grammar school was promoted to main grammar school, initially housed in the upstairs halls of the Great School. Here the writer Zilahy Lajos, the professor of medicine Dr. Kiss Ferenc, and the graphic artist Major Henrik studied. On 15 September 1970, the sixteen-room modern institute with specialised rooms and central heating began to operate. The new school has been in existence since 18 November 2010, as the successor to the Arany János Grammar School and the Arany János Elementary School. Education started on 1 September 2011.

The Tower is all that remained of the former Salonta Castle. The construction of the castle started around 1620 and it was mentioned in the battles against the Turks in 1636. In 1658, Prince Rákóczi György II of Transylvania had it demolished to prevent it from falling into Turkish hands.

In 1899, the Truncated Tower was raised and the Arany János Museum was opened in it. Above the entrance is a seated statue of the Hungarian poet.

The sculpture by Antoinne Durenne is the oldest statue in Nagyszalonta. The statue was erected on the first Artesian well in the town. Hebe is the Greek goddess of youth, daughter of Zeus and Hera, wife of Heracles. Locals call her Iron Mariska (nickname for the name Mary).

The house was built in 1912. It belongs to the Arany János Cultural Association. It was built as a tenement house by the association to maintain the museum from its income. On its walls are plaques commemorating Bocskai István, Lovassy László and Földi János.

Lovassy László was a reformist Hungarian politician. At the suggestion of Baron Wesselényi Miklós, they founded the Association for Social Conversation, advocated a solution to the serf question and helped Polish refugees. On 29 January 1836, after the violent dissolution of the Transylvanian Parliament, he made a revolutionary speech at a sympathy demonstration in Pest in favor of the detained Wesselényi Miklós. When Metternich violently dissolved the Hungarian Parliament in Pozsony, Lovassy blamed the king and the government for the unsolved serf question. He was accused of insulting his majesty and sentenced to 10 years' imprisonment in 1837. He was released by amnesty in 1840, but suffered from mental problems. He died in 1892 in Nagyszalonta.

The Hungarian astronomer Kulin György (1905-1989) was born and spent his youth here. He discovered 21 small planets and one comet. Since 27 April 1991, a bilingual plaque commemorates him on the wall of the house.

The house is marked by a commemorative plaque. The poet's original birthplace burnt down in 1823, leaving no trace of it, so it could not be reconstructed. The building on the site of the poet's former birthplace was bought by the municipality of Nagyszalonta in 1908. In 1909 a commemorative plaque was placed on the facade of the building. The building was completely renovated in 2010.

It is intended to present the childhood of Arany János, and contains no personal items. Arany János was born into an impoverished noble family.

Kiss István's work was inaugurated in 1992. The Hungarian poet was born in Nagyszalonta.

On 30 June 1901, the work of Tóth András, a sculptor from Arad, was unveiled. A replica of the artist's statue in Nagyszalonta was also erected in Cleveland in 1902, 50 years after Kossuth Lajos's tour of America. The sculptor is the father of the poet Tóth Árpád.

The bust of the great 19th century Hungarian poet was erected in 2007.

The statue was erected in 2000. It is the work of Kolozsi Tibor. Bocskai István was the Prince of Transylvania and the leander of the Hungarian War of Independence against the Habsburg. The town was founded by the hajdú warriors, who were settled by the prince in 1606.

The memorial was erected in 2006 to commemorate the "400 years of the town of Nagyszalonta". The town was founded by 300 hajdú warriors settled by Prince Bocskai István of Transylvania in 1606. It is located at the foot of two oak trees planted in the Elizabeth Park during the millennium celebrations in 1896. The monument depicts two hajdú soldiers standing in front of a double gate with the town's coat of arms.

On the right side of the Reformed Church there is a life-size statue of the Hungarian poet Arany János, busts of Sinka István, Zilahy Lajos, Kulin György, and Kiss István (sculptor), who was awarded the Kossuth Prize.

Kulin György was born in 1905 in Nagyszalonta, and he was a famous astronomer. He discovered several small planets and comets. The small planet he discovered on 11 December 1936 was named Szalonta.

The statue of Arany János next to it was made by the sculptor Kiss István.

Sinka István (1897-1969) was a Hungarian poet and writer, born in Nagyszalonta.

Zilahy Lajos (1891-1974) was a Hungarian writer born in Nagyszalonta. After the Second World War he emigrated to the USA.
