The basic idea of English gardens, landscape parks and woodlands was to avoid distorting nature. Walking paths and paths along the river, through woods or through ravines were to run naturally, as if they had been walked for hundreds of years. Fallen trees were to remain and be covered with moss. If any clean-up work was carried out, it had to preserve the untouched nature of the area. Scenic viewpoints and romantic resting places were allowed. The landscape park had to reflect the diversity and uniqueness of nature. On the banks of the Amata River near Karlamuiza, nature had created a unique opportunity for such a landscape park or forest park to exist. It had and still has everything: impressive sandstone and dolomite cliffs, breathtaking landscapes and bubbling rivers, a diverse chorus of birds and primeval ravines. The surroundings were so in keeping with the Enlightenment idea of a park or garden that the owners of Karlamuiza had to make little effort to create walking paths, trails and romantic resting places to make the place unforgettable for the many guests and travellers to the manor. The late 18th century the landscape park of Karlamuiza was an outstanding example of the best taste and appreciation of beauty of its time.

In 1819, the manor was bought by a Russian colonel, Count Joseph von Koskul.  He extended the central part of the manor with new buildings - stables, cattle barn, inn, gardener's house, watermill and housing for the families of the manor workers. Today, the Karlamuiza Country Hotel is located in the former apartments of the gardener families, built in the mid-19th century. Each family had a bedroom, a kitchen and a small cellar - a pantry. Every family apartment was equipped with a room, a tiny pantry and a kitchen, its own entrance, stove, and chimney. The same entrances and chimneys have been preserved and restored today.

His only daughter Elisabeth married Count Emanuel von Sievers, grandson of Karl Eberhard von Sievers, and after the death of Josef von Koskula in 1863, Karlamuiza again became the property of the Sievers family.

The third important historical event is the establishment of the first horticultural schools and one of the largest horticultural farms in the Baltics

In 1871, the first gardening school in the Baltics was established in a converted inn building and the institution was granted the status of a two-year horticultural school (In 1890); its graduates were qualified horticulturists. The school was subsidised by the state. In the 1890s, the Latvian painter R. Perle (1875-1917) trained as a gardener.

Fruit trees, berry bushes, park avenue trees, ornamental shrubs, roses, etc. were grown for export. On an area of 60 hectares, around 30 000 marketable plants were produced every year and a catalogue was published each August to advertise the produce. The nursery was one of the largest in the Baltics and offered a very wide range of products.

Damages in the 20th century

The first damage to the central building of Karla Manor was caused during the 1905 Revolution, when the beautiful manor house was burnt down. Thanks to the contribution of the owners, the building was restored. Karlamuiza suffered even more damage after the First World War; in June 1919, during the Latvian War of Independence, the manor house was reduced to ruins for the second time. It was never rebuilt.

During the Soviet period, the 'Red Flag' collective farm was established on the basis of the Karlamuiza horticultural and pomological garden, during which the chokeberry and apple orchards were preserved and extended.  After the collapse of the Soviet Union, none of the former structures of the manor farm existed and only the Karli fish farm, which was located in the old manor mill, continued its economic activities. The fish farm supplied the area back then and still does today and continues to release a lot of trout juveniles into nearby rivers, so the trout will never be out.
