Julianapark Main entrance Burg. Knappertlaan The Julianapark is the only park in Schiedam that is protected as a monument. Nowadays, its design is still very similar to the design that the municipal landscape architect J.K. Dominicus drew in 1914. The park was the first part that was constructed during the development of the new West district. The pond was an important part of the water management in the former polder area, which was reclaimed from 1907 onwards. Dominicus designed a park with curved paths in a landscaped design, combined with several formal avenues and sight lines, such as the access path from Burgemeester Knappertlaan. An artificial hill or belvedere was constructed in the centre of the park, from where there is a beautiful view of the park. The crowning dome is surrounded by a brick pergola. The colonnade with lime trees is also characteristic. There are more beautiful trees in the park, such as a beech and hornbeam, and the liberation tree planted in 1947. There are several monuments in the park, such as the Emmabank from 1935 and a liberation monument from 1949 by Pieter van Starreveld. Many older Schiedammers still remember the magical lighting of the Julianapark during the 'Holiday Festivities' in the fifties. This lighting was not easy, for example the eight kilometres of electricity cables had to be buried in lawns, flower beds and paths. The manager was therefore not initially enthusiastic. With Winterlicht in December the beautiful effect can be relived. NB. Fortunately this lighting was not always on. The adult male youth had secret meetings in the park at night with the young student nurses who stayed in the convent next to the park.

An insect hotel is a structure that is specially designed to provide shelter and nesting places for insects. It is often used in gardens, parks or natural areas to support biodiversity. Here is more information about insect hotels: Purpose of an insect hotel • Supporting biodiversity: Insect hotels help beneficial insect species such as bees, ladybirds, lacewings and earwigs to survive, especially in urban or agricultural areas where natural shelters are scarce. • Pollination: Solitary bees, which often use insect hotels, play an important role in pollinating flowers and crops. • Pest control: Some insects, such as ladybirds and earwigs, eat pest insects such as aphids, which can help to naturally maintain plants. Construction of an insect hotel An insect hotel consists of several compartments, each suitable for different types of insects. Commonly used materials include: • Wooden blocks with holes drilled into them: For solitary bees, such as the mason bee. • Hollow stems: Bamboo or reed for small bee species. • Pine cones or straw: For ladybugs and earwigs. • Bark and twigs: For spiders and other small insects. • Loam or clay: For bees that seal their nests with mud.

Along the Oostdijk between the Tonnekreek and Willemstad is 'De Wachter' a special work of art. De Wachter stands exactly on the spot where the storm surge on 1 February 1953 hit and flooded the Ruigenhilpolder. The work of art is an eight-metre-high hill, on which sheep can graze. The work of art De Wachter, by artist Marius Boender, was built along the Hollandsch Diep at the spot where the dike broke during the Flood Disaster in 1953. The reason for the monument was the completion of the dike reinforcement in 2001. The work of art is an eight-metre-high, pyramid-like clay hill, overgrown with grass. You can climb the work of art via a path that winds over the work of art. There is a good chance that you will do so in the company of grazing sheep. The creation of the work of art was a challenge, because factors such as weight (not too heavy), weather resistance (rain and wind) and construction (not subsidence under pressure from visitors) had to be taken into account.

The nature reserve of the Tiendgorzen is located on the Haringvliet next to the ferry to the island of Tiengemeten. The rare Arctic vole has been living in the wetlands of Tiendgorzen for several years now. The animal feels completely at home in the nature of the marshy grass and reed land. There are also many birds in Tiendgorzen. For example, reed birds and waders such as the reed warbler and redshank are frequent visitors. [natuurmonumenten.nl]

Arable lands full of poppy, cornflower and yellow goose flower. The farmer used to harvest grains, including weeds. He saved part of the harvest for sowing again the following year. In addition to grain, the wild field flowers also reappeared. Nowadays, the foresters are actively working on the return of field flowers to restore the agricultural image of the past in the Oude Polder.
