The beauty of Kaštela and the Field of Kaštela inspired many poets who described their beauty in many poems.
"Seven villages like seven swans" became a motto of the town of Kaštela. In the most parts of the Field of Kaštela vineyards, olive groves, cherries, figs and autochthonous Mediterranean vegetation trade places with monuments of natural heritage and park architecture.
An olive (Olea Europea), more than 1500 years old grows in Kaštel Štafilić, which people of Kaštela call Mastrinka. It is considered that it was brought from Southern Italy or Greece. Due to the fact that estates of the Roman were in this area, it was presumed to be a remnant of an agricultural estate from those times. The olive is of an oil-producing species with small leaves and fruits. The system of roots occupies space of more than 100 meters. The span of the tree is 6 meters, the span of the tree top is 22 meters and the height is 10 meters. Annual crop of olives is processed into oil and packed into replicas of glass lacrimatoriums as an autochthonous souvenir of Kaštela.
An oak (Quercus Pubescens Willd) by the Romanic church of St. Kuzma and Damjan in Kaštel Gomilica capture interest by its beauty and size in this old Kaštela surrounding.
Park around the Palace Hotel in Kaštel Stari is also a monument of park architecture. It was founded in 1910 by Dr. Petar Kamber, former owner of the hotel and a man fond of Kaštela. The park stretches on 35 000 square meters.
