• Limestone was quarried in Kalana for von von Lauw's glass industries.
• The stone extracted in Kalana was referred to as “Kalana marble.”
• The Umbusi jõgi rises from the Kalana allikas spring and is publicly accessible.
• Otissaare Hillfort dates from the 11th century and is designated as a place with beautiful views.

Limestone is connected with the industrial history of the place. It was quarried in Kalana for von von Lauw's glass industries. The stone obtained from it was referred to as “Kalana marble.” Those interested in the history of materials, geology or the use of regional raw materials will therefore find a concrete way to engage with the history of the place here.

The Kalana quarry is also important from this perspective. Fossils of nautiloids, snails, corals, crinoids, brachiopods, sponges, trilobites and graptolites have been found there. The quarry is also described as the richest site for fossils of algae species. This diversity makes the site particularly interesting for travelers who want to combine nature observation with a geological focus.

The Umbusi jõgi rises from the Kalana allikas spring. The Umbusi jõgi contains a protected spawning and habitat area with the identifier KLO3002592. At the same time, the Umbusi jõgi is publicly accessible. For your travel planning, this connection with the landscape offers another way to understand Kalana not only through its architectural and industrial history, but also through its bodies of water and habitats.

You should consider the information about the river, spring and protected area separately from the historical sights. This keeps the selection clear: the quarry represents fossils and limestone, the Umbusi jõgi the landscape, and Otissaare the hillfort, views and history.

Otissaare Hillfort dates from the 11th century. It is also designated as a place with beautiful views. Kalana linnamägi Hillfort is also called Otissaare mägi; at 82.3 m, it is the highest point in the region and clearly recognizable in the landscape. If you want to combine historical sites with views of the landscape, this complex is one of the central themes for exploring Kalana.

If you are primarily interested in fossils, the quarry and Kalana marble are the main attractions. For a nature-focused stay, you will be more likely to plan around the Umbusi jõgi and its source. The hillfort adds a historical dimension to these themes.
