Eden Project - the Cornwall Peninsula peculiarity
(2012) Baczyńska, Elżbieta; Lorenc, Marek Wojciech
The Eden Project-the largest natural scientific complex - was established in 2001 in the surroundings of Bodelva situated in the southern part of Cornwall (Great Britain). It was created in a kaolin pit closed down in the XlXth century. This venture has three main functions: natural, educational and touristic. The project presents unusually interesting and original architecture. Under light-transmitting, semicircular domes there are various ecosystems called biomes which differ from the external environment. The entire project consists of the following parts: the Mediterranean biome, the rainforest biome, a unit called »the Core« and the visitor centre. The area where all the buildings are located is covered by the external biome. The Eden Project is a huge educative institution which reflects processes occurring in the nature. The aim of this venture is, above all, education of ecological aspects concerning life on the Earth and presentation of the necessity to preserve the biodiversity. Since its opening, the Eden Project has been visited by 1.2 million tourists every year.

Gökçeada - a Turkish island on the Thracian Sea
(2013) Lorenc, Marek Wojciech
Gökçeada is the biggest of all Turkish islands situated on the Thracian Sea about 20 km west of the Gallipoli Peninsula. Archaeological discoveries have so far indicated that colonization on this island dates back to 3000 BC. Currently, about 8300 people live on Gökçeada, including about 250 inhabitants of Greek origin. The diversity of the island's geological structure affects its rich relief and area colouring. Cliffs on the northern coast and beaches on the southern one, high mountains and deep canyons in the central part of the island attract fans of solitude, diving and nature. Monuments from the time of the Roman Empire are rare on the island. One of them is a huge rock with two tombs hewn out in it. It is located in a completely uninhabited and treeless area. There are seven old plate trees on the island registered as natural monuments. The youngest one is 180 years old and the oldest tree is almost 630 years old.

Nieczynny kamieniołom bazaltu w Strzegomiu - szansa na nowe otwarcie
(2010) Tokarczyk-Dorociak, Katarzyna; Skolak, Krzysztof; Lorenc, Marek Wojciech
The paper presents the history, current state and possible future protection, and development of the open-cast mining heritage. An example is the abandoned basalt quarry in Strzegom known under official name »The Żółkiewka Quarry« although local community uses rather the term »basalt quarry«. The rock is an Early Miocene alkaline basalt of K-Ar isotopic age 19.84 - 0,93 Ma. Mining operations had lasted from the XlXth century until 1986. The plans are currently prepared to adapt the quarry for local community and for tourism by development of geological thematic trail and construction of educational infrastructure.

Problem niewykorzystanego potencjału dawnych kamieniołomów na przykładzie Wieżycy i Chwałkowa (Dolny Śląsk)
(2010) Krawczyk, Elżbieta; Lorenc, Marek Wojciech
The proper development of abandoned mine workings is the aesthetic, environmental and economic problem. Abandoned quarries are subjected to natural remediation by reconstruction of groundwater table and expansion of plants. Troubles arise when abandoned quarries become illegal landfills and when steep, commonly vertical, unprotected walls, and/or deep reservoirs may become lethal traps. However, the same, hazardous elements: walls and reservoirs can be attractions for both the local residents and the tourists. Values of abandoned quarries were appreciated and developed in the past with positive effects. The authors present examples of two quarries from the vicinity of Ślęża in Lower Silesia, which should encourage us to consider such sites as elements of local economy and to perceive their undeveloped potential.

Torcal de Antequera - kamienne miasto w Andaluzji
(2010) Janusz, Małgorzata; Lorenc, Marek Wojciech
The Torcal de Antequera is one of the best-preserved karst landscapes in Europe developed in Jurassic, oolithic, brecciated and detrital limestones. The rock formation is well bedded and cut by a dense, regular fracture system. A relatively small area (20 km$^{2}$) comprises four distinct geomorphological zones. At the surface visitors can recognize a variety of landforms produced by water and wind erosion whereas underground there exists a labirynth of karst forms: deep shafts, meandering galleries and huge caves. Since 1978 the Torcal de Antequera has been protected as a Natural Park and since 1989 it has become a Nature Site. The park combines a collection of remarkable geological valours and an exceptional biodiversity.

Wybrane, nowe propozycje atrakcji geoturystycznych z Dolnego Śląska
(2010) Lorenc, Marek Wojciech; Mazurek, Sławomir
The Lower Silesia is the region of the largest diversity of igneous, sedimentary and metamorphic rocks used for construction and decoration. These rocks are extracted in numerous quarries, which are generally inaccessiblefor tourists. Hence, the educationally important, unique or just interesting sites remain unknown and cannot be included into the educational activity. However, there is a great number of abandoned quarries, which have been densly vegetated since the closure and which were rather distant from popular tourist trails. Among them are many sites of significant historical value due to the age of exploitation or particular stones then used for construction of important historical monuments or for carving the stonework or sculpture masterpieces. The following paper presents the currently operating quarries with the reference to modern buildings in Wroclaw, in which specific stones were used. Moreover, the abandoned quarries were described, which may become tourist and geotourist attractions if properly developed and provided with relevant information.
