ATOS Centar za događaje, the ATOS event center, is a venue in Čelinac, Bosnia and Herzegovina, that hosts weddings, birthdays, anniversaries, conferences and seminars. The official site gives a capacity of up to 600 guests. It stands at Majdanpečka 9, 78240 Čelinac, and offers six guest rooms on site.
Seminars and company events
The center lists conferences and seminars among the events it takes. The site describes the venue as modern, with professional staff, air conditioning, free Wi-Fi across the building and audio and video equipment that supports technical needs. These are the basics a seminar needs. The site does not break the venue down into meeting rooms, so ask for the layout, the number of seats in classroom or theatre style and the equipment included when you send your request.
Weddings and receptions
Weddings are the first event on the list. The wedding section gives the capacity of up to 600 guests. Christenings, birthdays, anniversaries and other celebrations follow. The team offers decoration and interior styling to match the theme of each event, so the room can be set up for a ceremony, a dinner or a party. A couple or a company can therefore ask for one setting for the ceremony and another for the meal, within the limits the team confirms for the date.
Rooms and capacities
The site presents a single venue and does not name separate halls. The figure to keep is 600 guests for the largest events. Smaller groups should ask what part of the venue is used for them and how the room is laid out. The 600 figure covers the whole venue, so a seated dinner or a classroom seminar will hold fewer people. Ask for the number that fits the layout you need, and for the date options.
Accommodation
The center has two three-bed apartments and four double rooms, so guests of a wedding or a seminar can stay on site. That is room for around 14 people in the stated beds. The apartments are described as furnished to modern standards.
Catering
The site does not say whether catering is in-house or whether an outside caterer is allowed. Ask about this before comparing the venue with others, because it affects the layout and the budget of the event.
