Grignano: Miramare Castle, Park and BioMa

With Miramare Castle, its park and BioMa, Grignano offers several distinct highlights for a stay. The residence stands at the tip of the Grignano Karst peninsula. The focus is therefore both on the castle’s architectural and collection history and on its gardens and the environmental interpretation of the marine protected area. To help plan your visit, decide in advance whether you would like to spend more time on the architecture, the park or marine topics.

Miramare Castle: Building History and Collections

Miramare Castle was built between 1856 and 1860 as the residence of Archduke Maximilian of Habsburg and his wife, Princess Charlotte of Belgium. It stands at the tip of the Grignano Karst peninsula. The castle is built from Istrian stone in an eclectic style; the design was overseen by Austrian engineer Carl Junker. Its construction period, patronage and architecture give Miramare a clearly defined historical perspective.

The castle’s rooms display caskets, clocks, chinoiserie and archaeological finds. The topics range from the building’s architecture to a variety of collection items. Carl Junker also designed the Miramare stables, which were built between 1856 and 1860. Their shared design and construction period offers a concrete point of comparison with the residence. The Miramare greenhouses were intended for experimental botanical activities, adding a botanical perspective to the castle’s history.

The Park and Its Botanical History

Miramare Park covers 22 hectares. It combines elements of an English landscape garden with formal, geometrically arranged areas in the parterre. This contrast makes the garden a subject in its own right alongside the castle’s interiors: the gardens showcase different forms of landscape design, while the castle focuses on architecture and collection items. Together, the park and castle offer different perspectives on Miramare, without either replacing the other.

BioMa and the Marine Protected Area

BioMa is located in the right wing of the former stables of Miramare Castle, a five-minute walk from the Habsburg residence. It offers year-round immersive environmental interpretation of the Gulf of Trieste and the Miramare Marine Protected Area, from the sea surface to the depths of the sea. BioMa also includes a special touch pool with benthic organisms.

Guided visits to BioMa last an hour and a half. Schools, groups and associations can request them by arrangement. If you are planning a group visit, allow for this duration and make your request in advance. Seawatching takes place each year from June to September in small groups accompanied by WWF staff. Check the schedule for the relevant season if you are planning your trip around it.

The buffer zone of the Miramare Marine Protected Area covers 90 hectares and is 400 metres wide. All forms of fishing are prohibited there, except shore-based recreational fishing; anchoring is also prohibited. If you are planning water activities, observe these rules and check the local notices on site.

Access and Getting There

The western entrance to Miramare Park is located at the port of Grignano. Some regional trains stop at Miramare station. From there, it is a two-minute walk through the upper entrance to the park; continuing through the botanical garden to BioMa takes 15 to 20 minutes. Bus route 6 runs from Trieste towards Grignano; route 51 goes from Trieste Airport or Monfalcone to Miramare.

Before travelling, check the latest train and bus connections and the park access information. This will help you plan your routes and visit to BioMa according to your interests.
