In 2005, St. Ottilien Archabbey handed over an album of 21 ink and color on silk paintings by Korean master Jeong Seon (1676-1759) as a permanent loan to Waegwan Abbey. The paintings are kept safe at the National Museum of Korea.

We suppose Archabbot Norbert Weber acquired the album on his second mission travel in 1925. One of the paintings is depicted and mentioned in his travel diary "In den Diamantbergen Koreas" (In the Diamond Mountains of Korea). It is uncertain if the album was already bound or was composed later by Norbert Weber.

However, the different motifs suggest, that the paintings originally did not come from one source. Traditionally, albums are composed of only one subject. Among the 21 silk paintings, there are five "true-view" landscapes, three ideal landscapes, one animal painting and 12 illustrations of historic people with scenes from their lives. 

The collection was presented at the St. Ottilien Mission Museum for a long time. Graduate student Yoo Jun-yeong, later a professor at Ewha Woman's University in Seoul, discovered the album in 1975 during studies for his doctoral thesis in Germany. He took notice of Archabbot Norbert Weber’s travel diary.

In 1977, the delicate silk paintings were restored professionally on the initiative of St. Ottilien's Archabbot. An article published in 1999 in the "Oriental Art" journal by Kay E. Black and Eckart Dege put the album on the map internationally. 

After counsils at St. Ottilien's religious community, the album was handed over as a permanent loan to Waegwan Abbey, as it is an eminent national Korean art treasure of great value.

The album was presented to the public by the National Museum of Korea in several special exhibitions. The most famous of the silk paintings with an overview of the Diamond Mountains was part of an exhibition at the Metropolitan Museum of New York in 2018.

The Herbarium of Korean Plants consists of 420 single pages with plants from the area of today's North and South Korea.

Fr. Andreas (André) Eckardt OSB (1884-1974) collected the plants in 1913 during his activities in the Korean mission and brought it later to St. Ottilien.

Every plant is professionally mounted on paper and states the scientific name, date and collecting area. In the regions of today's North Korea, Eckardt collected plants at Suwon, Gyeonggi, Wonsan, Pyeonggan and in the Diamond Mountains; amongst others, he found specimens of the endemic Diamond Bluebell Hanabusaya asiatica (called geumgang chorong in Korea).

A collection example from today’s South Korea is Pteris excelsa, a type of fern out of the Pteridaceae family, which Eckardt collected on Jeju Island. This plant is known as an endemic species but could not yet be evidenced.

The herbarium was transferred to Waegwan Abbey in 2005. In 2015, the Mission Museum donated it to the Korea National Arboretum near Seoul. This governmental organization is committed to scientific research and conservation of the Korean plant stock.

It was the first time Korea received a botanical collection with endemic plant material from foreign sources.

One leaf of the herbarium was preserved for exhibition. The page no 1001 shows leaves and fruits from the East Asian eurya (Eurya japonica). The Latin inscription of the page indicates that the plant was collected by Fr. Andreas Eckardt in 1913.

On the back panels of the Korean "Complete Map of the World" (Gonyeo jeondo) from 1860 presented in the basement of the Museum, the genealogy of a family from South Korean Iksan province was written down.

During restoration of the map, the panels were dismounted from a folding screen and the rear panels could be separated.

Supposedly, Archabbot Norbert Weber is the collector of the map; however, no hint can be found in the museum's archives.

The genealogy written with ink in Chinese letters was donated together with the frames to the South Korean governmental organization Cultural Heritage Administration. The research of the family tree is still ongoing.

Fr. Canisius Kügelgen OSB (1884-1964) worked from 1911 to 1950 in Korea. He was an apiarist and wrote the manual "brief summary of beekeeping" (yangbong yoji) at St. Benedict Abbey in Seoul in Korean language.

Kügelgen's book was hectographed, i.e. duplicated with a matrix (template), and sent to some monasteries founded by St. Ottilien Archabbey, among them Münsterschwarzach. From their library, a copy of the book was transferred to Waegwan Abbey, which handed it over to the Republic of Korea as a permanent loan. The copy presented in the special exhibition is part of St. Ottilien Archabbey's library.

The history of beekeeping in Korea dates back 2000 years to the early Gogurye kingdom (37 BC - 668 AC). Today, the Eastern Honeybee (Apis cerana) is still housed in so-called log hives, hollow tree trunks, in Korea's mountainous regions.

Fr. Canisius Kügelgen was one of the pioneers who brought the Western Honeybee (Apis mellifera) to Korea. This bee species was established in many countries around the world because it is less aggressive and produces more honey.

In 2018, the Mission Museum donated a Korean military overcoat, the so-called Blue Harness, to the governmental organization Overseas Korean Cultural Heritage Foundation.

The harness, which was worn by infantrymen, is made of almost marine blue dyed cotton fabric and decorated with a pattern of lotus flowers. On the inside, breast, shoulder and back areas are reinforced with square leather patches. These patches did not hold back arrows completely but prevented deep penetration. The inner lining is printed with a flower pattern. It is unusual that the name of the owner can be found on the inside.

The age of the overcoat is dated end of the 18th or beginning of the 19th century. It was acquired by Archabbot Norbert Weber OSB (1870-1956) on one of his two mission travels to Korea.

The harness is in a rather bad state; some leather patches are loose, the silk lining is frayed and the iron studs left traces of rust on the fabric. Nevertheless, it is very valuable as a research object; only a few of this type of military overcoat are still in existence in Korea.

The Overseas Korean Cultural Heritage Foundation arranged for the creation of an exact replica, which was exhibited in the special exhibition.
